Fix Boot Device Not Found Error in Windows
If you encounter an error saying, “Boot Device Not Found” when you turn on your Windows 10 computer, then you’ve come to the right place as this post will guide you on how you can fix this problem. Apart from the error message, you will also see a message that states, “Please install an operating system on your hard disk, Hard Disk<xxx>”. You will then be asked to tap the F2 key to initiate the System Diagnostics. If you install the Windows operating system, it becomes the boot device, and when your computer boots, the UEFI or the BIOS looks for the operating installed on your drive and continues the process. So when you encounter the “Boot Device Not Found” error, this means that the UEFI or the BIOS wasn’t able to locate the drive where it can boot. There are several suggestions you can check out to resolve this error. You can try checking the connection with your boot drive or change the boot order. You can also fix the Boot Record from Recovery and see if the primary partition is active or not. But before you troubleshoot the problem, make sure that you have a bootable Windows USB drive ready since two of the options provided below will require you to boot into the Advanced Recovery mode. Once you have this covered, proceed to each one of the following options.

Option 1 – Try checking the connection with the boot drive

If you have a custom computer that comes with a cabinet, you might want to open it and remove any connected power supply, and then check the wires. As you know, drives are connected with the motherboard using a cable. So all you have to do is check if both ends are connected properly and make sure that the connection is not loose. You could also try to unplug the cable and plug it back in.

Option 2 – Try changing the boot order

You might also want to try changing the boot order of your computer. Each time a computer boots, the BIOS or the UEFI follows a boot order. It is the one that tells where to first look for the boot drive and if for some reason, a USB is connected to your computer and the first boot device found in the USB, then you have resolved the problem. All you have to do is to remove the USB device and boot or go into the BIOS and change the boot order yourself.

Option 3 – Try to rebuild the BCD files

The next thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.
  • You can start by booting into the installation environment for Windows 10 from an installation media.
  • After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
  • From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
    • bootrec /FixMbr
    • bootrec /FixBoot
    • bootrec /ScanOS
    • bootrec /RebuildBcd
  • Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed the “Boot Device Not Found” error.

Option 4 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:
  • Boot your computer using the bootable Windows 10 USB drive.
  • Next, click Next when you get to the Welcome Screen.
  • Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
  • After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.
diskpart
  • Now type the following command:
list disk
  • From there, select your primary disk by typing the following command:
select disk number
  • After that, list all the partitions on the selected disk by entering the following command:
list partition
  • The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
  • Now type the following command to select the partition that is usually around 100 MB in size:
select partition number
  • Finally, type the following command to mark the partition active:
active
  • Then type the “exit” command to exit the disk part utility.
Once it’s done, the primary drive should now be active and you should now be able to boot into your computer without the “Boot Device Not Found” error.

About Adware

Exactly what is Adware? If you have ever owned a computer, then you’ve probably heard the word numerous times, but it is still beneficial to define it. The term “adware” is actually a short form of advertising-supported software and it includes programs that are solely designed to display ads on a computer. A kind of malware, it will come bundled right in with the software package that a user either installs or accesses. Shareware or freeware programs are often times packaged with adware. If adware penetrates your system without you knowing and sends information about you or your PC to 3rd parties, then it is spyware. Quite often, adware changes your web browser settings to open pop-up adverts or modifies browser homepage and default internet search engine to some unwanted website. Adware is a common problem that affects a large number of PCs around the globe. If your computer doesn’t have any anti-malware software then it’s very likely it could get infected with adware as well as other malware.

Adware and its effects on your PC:

Adware could generate and display plenty of ads of all sorts which in turn disrupt the functions of your personal computer while browsing the net. Pop-ups might also show up on your computer’s desktop even when you’re not online. Adware results in a reduction of available memory and processing power, or resources. It also causes a slow net connection because adware consumes bandwidth whenever it retrieves adverts from the internet. Adware was originally created to support companies to generate income when they offer the software away free of charge. However, adware nowadays displays hundreds of adverts which will cause your PC to slow down and even crash.

Adware prevention:

As we discussed, adware could potentially be harmful to your computer, generally not by itself, but by bringing other problems to you. A top-quality antivirus program has the capability of permanently removing adware. We recommend Safebytes Anti-Malware, one of the top-rated anti-malware programs by world-renowned industry experts. It will act either as a preventative tool stopping websites or software installations that contain adware or as a removal tool for an already infected computer. To prevent adware, download software from websites that you trust. Never download from websites that you have never been aware of or tried before; Always study the end-user license agreement (EULA) of any application you want to install; You need to avoid freeware and shareware where possible; Lastly, watch out for ActiveX, since many adware and spyware companies make use of the technology to install their wares onto your computer system

Malware Blocking Internet And All Anti-Malware Software? Do This!

All malware is bad and the consequences of the damage will vary based on the specific type of malware. Some malware variants alter browser settings by adding a proxy server or modify the PC’s DNS settings. In these instances, you will be unable to visit some or all internet sites, and thus not able to download or install the required security software to eliminate the malware. So what to do when malicious software prevents you from downloading or installing Anti-Malware? There are a few options you could try to get around with this problem.

Remove viruses in Safe Mode

In Safe Mode, you can actually change Windows settings, un-install or install some program, and eliminate hard-to-delete viruses and malware. If the malware is blocking access to the internet and affecting the computer, launching it in Safe Mode will let you download antivirus and run a diagnostic scan while limiting possible damage. To enter into Safe Mode or Safe Mode with Networking, press the F8 key while the PC is starting up or run MSConfig and look for the “Safe Boot” options under the “Boot” tab. Once you’re in safe mode, you can attempt to install your anti-malware program without the hindrance of the malicious software. At this point, you could run the anti-malware scan to eliminate viruses and malware without hindrance from another application.

Switch over to an alternate browser

Some malware only targets certain browsers. If this sounds like your case, use another web browser as it could circumvent the malware. If you suspect that your Internet Explorer has been hijacked by malware or otherwise compromised by hackers, the ideal approach is to switch over to a different internet browser like Firefox, Chrome, or Safari to download your chosen computer security software – Safebytes Anti-Malware.

Create a portable USB antivirus for eliminating malware

Another solution is to make a portable antivirus program on your USB flash drive. Adopt these measures to run the anti-malware on the affected computer system. 1) Download the anti-malware program on a virus-free PC. 2) Connect the flash drive to a USB slot on the clean computer. 3) Run the setup program by double-clicking the executable file of the downloaded software, which has a .exe file format. 4) Select the flash drive as the destination for saving the software file. Follow the directions to complete the installation process. 5) Transfer the pen drive from the clean computer to the infected computer. 6) Double-click the Safebytes Anti-malware icon on the thumb drive to run the software. 7) Hit the “Scan Now” button to start the virus scan.

There’s no Incognito Mode in Chrome
As you know, just like other web browsers, Google Chrome offers Incognito Mode or private browsing which you can use to make sure that your browsing activities are not being tracked by any websites you visit and it also keeps targeted ads at bay. On the other hand, signing in to a website, even when in Incognito Mode is a different thing since that website can track your browsing activities. Thus, Incognito Mode is still useful especially if you want to browse the web safely and without getting tracked except when you log in to some site. However, there have been reports recently that Incognito Mode is missing in Chrome and users are clueless as to how or why it happened. If you are one of them, worry not for this post will walk you through what you can do if there’s no Incognito Mode in Chrome on your Windows 10 computer. This is an unusual and strange issue since the Incognito Mode in Chrome is available by default and you don’t have to do anything to enable it. It is possible that there might be corruption in the Windows Registry which caused the disappearance of Incognito Mode, worry not though for there are some tweaks you can apply to restore the missing Incognito Mode. To apply these tweaks, you need to create first a System Restore point, and then once you’re done, follow the instructions provided below carefully. Step_1: Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then hit Enter to open the Registry Editor. Step_2: Next, after opening the Registry Editor, navigate to this path – ComputerHKEY_LOCAL_MACHINESOFTWAREPolicies Step_3: From there, look for ChromePolicies and locate the DWORD named “IncognitoModeAvailability” and double click on it. Step_4: Edit the value of the “IncognitoModeAvailability” DWORD by changing its value from 1 to 0 so you can enable Incognito Mode in Chrome. Step_5: Once done, exit the Registry Editor and restart your computer and then check if you can now see Incognito Mode in Chrome. On the other hand, there is also another option that allows you to force open your Chrome browser in Incognito Mode. All you have to do is set the value of the “IncognitoModeAvailability” key to “2” instead of 0. This can be useful especially if you always browse the web in this mode. But you need to remember that you won’t be able to go back to the normal mode once you do this. Here are what the values of the IncognitoModeAvailability DWORD actually mean:
  • 0 – Incognito mode is enabled by default
  • 1 – Incognito mode is disabled
  • 2 – Chrome is forced to always open in Incognito mode

Bluetooth flaw, Android and Windows in danger
bluetoothResearchers have discovered 16 vulnerabilities in Bluetooth connections that could be exploited and make from minor to some serious damage to your device. The flaw can be used on chips manufactured by Intel, Qualcomm, and Texas Instruments while connecting to external devices like speakers, headphones, keyboards, mice, etc.

Who is affected?

Mentioned chips are used by many in a vast range of devices including big players with their products like Microsoft Surface laptops, Dell desktops, Samsung Phones, Google Pixel, and OnePlus handsets. The Bluetooth bug affects a wide range of devices, including smartphones, laptops as well as smart home gadgets. In total, more than one billion devices that rely on Bluetooth are believed to be impacted.

What is the damage?

The amount of damage possible with this flaw depends on the type of device with the chipset. Some devices can only be crashed after a specially crafted packet is sent to the flawed chip. If that's the case with your gadget, it can be easily resolved with a simple restart. With other devices, hackers can take advantage of the Bluetooth Classic flaw to remotely run malicious code. That could allow malware to be installed remotely. Researchers say vendors were informed about these issues months ago before the findings were published. The good news is this should have given plenty of time for the relevant patches to be pushed out that remedy the flaws. However, you'll need to make sure that you're running the latest version of the operating system to be protected by the patch crafted by the manufacturers.

Android Bluetooth threat

The researchers emphasize the lack of basic tests in Bluetooth certification to validate the security of Bluetooth Low Energy (BLE) devices. The BrakTooth family of vulnerabilities revisits and reasserts this issue in the case of the older, but yet heavily used Bluetooth classic (BR/EDR) protocol implementations. We would also advise users to disable Bluetooth on devices that do not need it. This way you can prevent attackers from sending you malformed LMP packets. Since BrakTooth is based on the Bluetooth Classic protocol, an adversary would have to be in the radio range of the target to execute the attacks. So, in a safe environment Bluetooth can be enabled.

Fix 0xd00000e5, 0x8007139f, 0x80090030 PIN
The quickest and easiest way to log into your computer is when you use the PIN feature in Windows 10. Even though it is a bit slower compared to biometric logins such as Fingerprint and Iris scanning that comes under Windows Hello, the PIN feature is definitely less complicated. However, just like any other module of the software, it is also prone to some errors. In this post, you will be guided in fixing several PIN errors such as 0xd00000e5, 0x8007139f, and 0x8009003. These errors could be caused at different points in time like when you change or create a PIN or when you log into your computer. To fix the 0xd00000e5, 0x8007139f and 0x8009003 PIN errors, there are various solutions you can try. You may empty the contents of the NGC folder or remove and change the PIN or the password. You could also use the Group Policy Editor or reset the ACLs in the NGC folder as well as run built-in tools like System File Checker and the DISM tool.

Option 1 – Take ownership of the NGC folder and delete its contents

  • Boot your computer first into Safe Mode.
  • Next, you need to take ownership of the Ngc folder first and you can do that using Command Prompt.
  • Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
  • After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
  • Next, type and enter this command: TAKEOWN /F C:WindowsServiceProfilesLocalServiceAppDataLocalMicrosoftNgc
  • Note that the <path> is the location of the folder or file in File Explorer.
  • Now type and enter this second command: ICACLS C:WindowsServiceProfilesLocalServiceAppDataLocalMicrosoftNgc /grant administrators:F
  • Finally, once the command has been executed, restart your computer.
  • Once your computer has restarted, delete all the contents in the Ngc folder and check if the error is now fixed.

Option 2 – Try to remove and change the PIN or password

The 0xd00000e5, 0x8007139f, and 0x8009003 PIN errors could be caused by some conflicting issues with the PIN or password you have set for the User Account of your computer. Thus, you have to remove or change the PIN or password to fix these PIN errors.
  • Remove the PIN by going to Settings > Accounts > Sign-in options.
  • From there, go to the PIN section and click on the Remove button.
  • You will be asked to verify your account to proceed in removing the PIN, enter your credentials.
  • Restart your computer and then set up a new PIN.
  • Once you’re done, restart your computer and check if the error is gone now.

Option 3 – Try to use the Group Policy Editor

  • Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
  • Next, navigate to this policy setting: Computer Configuration > Administrative Templates > System > Logon
  • After that, double click on the “Turn on convenience PIN Sign-in” option located on the right-side panel.
  • Then set its radio button to Enabled. You will see the following description when you do so:
“This policy setting allows you to control whether a domain user can sign in using a convenience PIN. If you enable this policy setting, a domain user can set up and sign in with a convenience PIN. If you disable or don’t configure this policy setting, a domain user can’t set up and use a convenience PIN. Note: The user’s domain password will be cached in the system vault when using this feature. To configure Windows Hello for Business, use the Administrative Template policies under Windows Hello for Business.”
  • After setting the radio button to Enabled, it will turn on the Logins in your computer using the PIN.
  • Close the Group Policy Editor and restart your computer for the changes to take effect.

Option 4 – Try to reset the ACLs in the Ngc folder

  • Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
  • After opening Command Prompt with admin privileges, execute this command: C:/Windows/Service/Profiles/Local/Service/AppData/Local/MicrosoftNgc /T /Q /C /RESET
  • The command you entered will start checking for errors and fix them automatically.

Option 5 – Run the System File Checker scan and the DISM tool

System File Checker:

  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Now restart your computer.

DISM tool:

  • Open Command Prompt.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • Dism /Online /Cleanup-image /Restorehealth
  • After that, wait until the process is finished and do not close the window as the process will probably take a couple of minutes.
  • Once it’s done, restart your computer.

Removing Search.schooldozer.com hijacker

What is Search.schooldozer.com? And how does it function?

Search.schooldozer.com is a browser extension that functions as a search engine. It is developed and maintained by “Schooldozer”. It claims to improve users’ browsing experience by providing them with improved search results. However, it does not really do the things it claims to do. In fact, they’re quite the opposite ones – instead of improving the browsing experience, it makes users’ browsing experience unsafe and full of sponsored content. This is in contrast to what it states in its Privacy Policy:
“Install applications the easy way and without the hassle, using the Schooldozer downloader. The Schooldozer platform stems from years of experience with installing applications, resulting in a highly optimized process, yielding faster downloads, better user experience, and more successful installations.”
In addition, once installed Search.schooldozer.com is installed, it will change the default settings of a browser such as the default search engine, homepage, and new tab page. This is why security experts regard this browser extension as a browser hijacker and a potentially unwanted program. The modification of the browser's settings allows it to control users’ browsing by redirecting them to sponsored sites as well as deliver sponsored content from its affiliated sites in order to gain profit via pay-per-click marketing. And if you think that the ads it displays are harmless, think again for some of these ads can redirect you to suspicious websites that might contain harmful content. What’s more is that this browser hijacker can also keep track and monitor all your browsing activities in order to obtain your browsing data like search queries, what sites you always visit, browsing history, browser type, OS version, and so on. The information collected is then used and may even be shared with its affiliated third parties to deliver more customized and personalized advertisements.

How is Search.schooldozer.com distributed over the web?

Like a typical browser hijacker, Search.schooldozer.com is distributed using the software bundling method where several unknown and unwanted programs are bundled in a software package. Thus when you install any software bundle, make sure to always opt for the Custom or Advanced installation setup rather than the quick setup to avoid installing unwanted programs like Search.schooldozer.com. To remove Search.schooldozer.com from your computer, follow the removal guide below carefully. Step 1: Start the removal process by closing all the browsers infected with Search.schooldozer.com. If you’re having a hard time closing them, you can close them using the Task Manager just tap on Ctrl + Shift + Esc. Step 2: After you open the Task Manager, go to the Processes tab and look for the infected browser’s process and end it. Step 3: Then close the Task Manager and tap the Win + R keys to open Run and then type in appwiz.cpl to open Programs & Features in Control Panel. Step 4: From there, look for Search.schooldozer.com or any unfamiliar program that could be related to it under the list of installed programs and once you’ve found it, uninstall it. Step 5: Edit your Hosts File.
  • Tap the Win + R keys to open then type in %WinDir% and then click OK.
  • Go to System32/drivers/etc.
  • Open the host file using Notepad.
  • Delete all the entries that contain Search.schooldozer.com.

Fix Error 0x8024a11a or 0x8024a112
What is Error 0x8024a11a or 0x8024a112 ? If you are trying to update your Windows 10 computer and just when you were done downloading the feature update and about to install it, you encounter an error message saying:
“We’re having trouble restarting to finish the install, Error 0x8024a11a, 0x8024a112, 0x80070005 or 0x80070032”
And so to fix this problem, this post will give you a couple of possible solutions. Refer to the options given below to get started.

Option 1 – Restart your computer many times

This is the first thing you can try since there are instances when the Windows Update process gets stuck for a minor thing and restarting the computer usually helps in resolving the issue. All you have to do is click the Restart now button. However, if it does not work, you can use the Power buttons from the Start Menu or WinX Menu. Aside from that, you can also use your power buttons such as Alt + Ctrl + Del to restart your computer. And during the boot process, it is recommended that you restart your computer in Safe Mode or even in a Clean Boot State. After that, you can restart your computer in normal mode. This will make sure that no third-party processes will be able to interfere with the Windows Update process. To put your PC in a Clean Boot State, here’s what you have to do:
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
  • After that, try to install the Windows Updates or upgrade again.

Option 2 – Try running the Windows Module Installer

The Windows Module Installer is a built-in service in the Windows operating system that could help you resolve the Windows update error 0x8024a11a or 0x8024a112. You need to make sure that this service is Started and that its Startup type is set to Automatic – you can do this via Services Manager or by executing the command given below in an elevated Command Prompt.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “command prompt” in the field and hit Enter to open Command Prompt.
  • And in the elevated Command Prompt type in the following command and hit Enter:
SC config trustedinstaller start=auto
  • After executing the command successfully, you should see the “[SC] ChangeServiceConfig SUCCESS” message on the Command Prompt window.

Option 3 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help in fixing the Windows update error 0x8024a11a or 0x8024a112.
  • Open the Command Prompt with admin privileges.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • exe /Online /Cleanup-image /Restorehealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Run the System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why you’re getting the errors 0x8024a11a and 0x8024a112. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 5 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows update error 0xca00a000. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 6 – Run Microsoft’s online troubleshooter

Keyboard shortcuts and hotkeys are not working
This post will guide you on what to do if your keyboard shortcuts or hotkeys are not working on your Windows 10 computer. A lot of users use hotkeys as they make things easier for them as they use their computer. However, there are instances when these hotkeys suddenly stop working. It’s actually one of the most common problems with keyboards. And so to resolve this problem, you can try out some suggestions prepared on this post.

Option 1 – Clean the keyboard keys physically

Your keyboard might not be working properly due to some dirt or other corrosion. First, you need to shut down your computer and then unplug the keyboard if you are using a desktop computer and then prepare it for cleaning. After that, use a small cotton ear cleaning tool to get between the creases and clean them. You can dip it slightly in alcohol to make it more efficient in cleaning dust and dirt. And if you can, you have the option to pull apart the keyboard completely and then wipe away all the corrosion from the inside. Once you’re done, put the keyboard back together and then plug it back into your PC. Now turn your PC on and check if the hotkeys are now working.

Option 2 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:
  • The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
  • After opening Settings, look for the Update and Security option and select it.
  • From there, go to the Troubleshoot option located on the left-hand side of the list.
  • Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
  • After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Try connecting the keyboard to a different USB port

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion.

Option 4 – Uninstall previously installed keyboard software

If you have been previously using another keyboard, it might be better if you make sure that the software for the old device has been removed since there are instances when multiple software can cause problems due to similarities in actions.

Option 5 – Update the keyboard driver

You can also update the keyboard driver to fix the problem. There are cases when an outdated or corrupted driver can fix the problem. To do so, follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
  • From there, look for the keyboard driver and click on it.
  • Next, right-click on the keyboard driver and select the Update driver option.
  • After that, click the “Search automatically for updated driver software” option to proceed.

Option 6 – Reinstall the keyboard driver

If updating the keyboard driver didn’t help, then you might want to reinstall it. How? Follow the steps below.
  • Tap the Win + R keys to launch Run.
  • Type in MSC into the box and tap Enter or click OK to open the Device Manager.
  • After that, a list of device drivers will be displayed. Look for keyboard driver, right-click on it and then select “Uninstall device”.
  • After that, unplug the device and restart your PC.
  • Then plug your device back in. Assuming your device is connected to your PC, open the Device Manager again.
  • Next, click on the Action button and click the Scan for hardware changes button. That should fix the problem.
Note: You could also completely uninstall the driver and go directly to the manufacturer’s website and download the latest driver for your hardware and then install it.

Option 7 – Enable Human Interface Device (HID) Service

Another thing to consider is the Human Interface Device Service. If this service is disabled, then no wonder why your hotkeys are not working. Thus, you need to enable this service. Refer to the following steps to do that:
  • Tap the Win + R key to launch the Run dialog box.
  • Then type “services.msc” in the field and hit Enter to open Services.
  • After opening Services, scroll down until you see the Human Interface Device service.
  • Double click on HID and make sure that its Startup Type is set to “Automatic” and then click OK.
  • Restart your PC and check if the hotkeys are now working or not.

Option 8 – Try resetting the keyboard

You might also want to try resetting the keyboard as it can also help in fixing the problem. Setting it back to its default state will surely help.

Fixing “The .NET Framework 4.7 is not supported on this operating system” Error in Windows 10
In case you don’t know, the .Net Framework is a programming infrastructure introduced by Microsoft. You will need it to run on lots of services and applications. Note that most of the applications that require the .Net Framework are packed with their installation files which is why it will be installed automatically on your computer when you install an application. However, there are instances when you’ll get an error message saying, “The .NET Framework 4.7 is not supported on this operating system” while trying to install the .NET Framework as a standalone service. The very reason why this error message appears is stated in the error message itself. Although the .Net Framework is supported on Windows 10, it is not actually compatible with some other Windows 10 versions. So it is most likely that you are seeing this error message because the .Net Framework in your computer is not compatible with the Windows 10 version you are running. Since that’s the case, you need to update Windows 10 to fix the problem. Updating your Windows 10 computer is the only solution you can try to fix this problem. Thus, it is advised that you check for Windows Updates even if you are now using the latest version of Windows 10. And since the issue is caused by an incompatible operating system version, once you install the exact version of Windows 10 required by the .Net Framework, the problem will be fixed. Simply follow the steps given below to do so.
  • Step 1: Tap the Win + R keys to open the Run dialog box.
  • Step 2: After that, type in “winver” in the field and tap Enter.
  • Step 3: Next, your Windows 10 version should be given in the new window that appears. Take note that the number after the Version which is in the second line is your version number of Windows 10. And that the number must be 1507 or 1709. The first two digits in these numbers are the year while the second two represent the month when the update was released. So if you are running a 1709 version, this means that the Windows 10 version you are using was released in September 2017.
  • Step 4: The next thing you have to do is to make sure that you have the Windows 10 version that’s compatible with the .Net Framework. To verify, you need to click here and click on the System Requirements.
After opening the link, take a look at the Supported Operating System section where it says, “Windows 10 Anniversary Update” and “Windows 10 Creators Update”. Since there are users who are not familiar with the version numbers related to both the Anniversary and Creators updates, refer to the list given below.
  • November Update (1511)
  • Anniversary Update (14393)
  • Creators Update (1703)
  • Fall Creators Update (1709)
  • Spring Creators Update (1803)
As you can see, the Creators Update has version 1703 while the Anniversary Update has version number 14393 so if you are using a version lower than the 14393 version then it’s no wonder you aren’t able to install the .Net Framework 4.7 on your Windows 10 PC. Now all that’s left to do is to update your Windows 10 version and make sure that you will be updating it to the latest version available and then try installing the .Net Framework again.
