As you know, one of the most highlighted features of Windows 10 is Windows Updates. It was offered to the customers as a service rather than a product with the release of Windows 10 under the scenario of Software as a Service which led to Windows Updates being set by default on Windows 10 and without an option for any users to disable it. Although not all users are happy with what Microsoft did, this is an ultimate step towards the greater good of all its customers since Windows Updates helps users in keeping their computers secured against all kinds of threats as well as provide them with the greatest and latest updates from Microsoft. So if you are one of those users who approved of the Windows Updates service, then read on as this post will guide you in running Windows Updates from Command Line either via Command Prompt or Windows PowerShell. For the complete set of instructions, refer to the options given below.

Option 1 – Run Windows Update via Command Prompt

Command Prompt in the Windows operating system exists for a very long time now compared to the comparatively new Windows PowerShell. That’s why it has similar capabilities to run Windows Updates. However, the highlighting point here is that you don’t have to download any module for Windows Updates. To get started running Windows Updates using Command Prompt, refer to the steps below.

• First, type “cmd” in the Cortana search box, and from the search results, right-click on Command Prompt and select the Run as Administrator option to open it with Administrator privileges.
• If a User Account or UAC prompt appears, just click on Yes to proceed.
• Next, type in the commands listed below, and don’t forget to tap Enter right after you type each one of them.
  • UsoClient StartScan – use this command to start checking for updates.
  • UsoClient StartDownload – use this command to start downloading updates.
  • UsoClient StartInstall – use this command to start installing the downloaded updates.
  • UsoClient RestartDevice – use this command to restart your computer after you install.
  • UsoClient ScanInstallWait – use this command to check, download and install updates.

Note: Keep in mind that the commands in Command Prompt listed above are only meant for Windows 10. On the other hand, if you are using an older Windows version, you can try using the following commands instead:

• wuauclt /detectnow – use this command to start checking for updates.
• wuauclt /updatenow – use this command to start installing the updates detected.
• wuauclt /detectnow /updatenow – use this command to check, download and install updates.

Option 2 – Run Windows Updates via Windows PowerShell

If you run Windows Updates in the Windows PowerShell, it will require you to install the Windows Update module manually. Hence, you have to get the Windows Updates downloaded and install Windows Updates.

• Search for PowerShell in the Cortana search box and then run it with administrator privileges.
• Once you’ve opened the Windows PowerShell, type the following command and hit Enter.
  • Install-Module PSWindowsUpdate – use this command to install the Windows Update module for Windows PowerShell.
  • Get-WindowsUpdate – use this command to connect to the servers of Windows Update and download the updates if found.
  • Install-WindowsUpdate – use this command to install the Windows Updates you’ve downloaded to your computer.

This post will guide you in fixing high CPU, Memory, and Disk usage problems caused by NTOSKRNL.exe. NTOSKRNL stands for “NT Operating System Kernel. This file is a kernel image that is responsible for a lot of systems-based processes such as Hardware Virtualization, Process, and Memory. Aside from that, it is also the one that compresses the old pages of memory that reduces the overall amount of memory being used. If you notice that your computer is running slowly and you find that the NTOSKRNL.exe file is hogging your resources such as disk usage, CPU usage as well as memory usage, then read on as this post will guide you in fixing the problem caused by NTOSKRNL.exe. Make use of the options given below to resolve the issues caused by NTOSKRNL.exe. 1] Scan your computer for potential malware There might be a good chance that your computer might be infected with malware. And this malware might be associated with the NTOSKRNL.exe file and hence making it consume a lot of system resources. So, I would really recommend you to make sure that your Antivirus is up to date and then scan your computer with it specifically the C:/Windows/System32 folder because this is the location where the NTOSKRNL.exe file is located.

Option 1 – Put your computer in a Clean Boot State

The first thing you have to do is to put your computer in a Clean Boot State as this can help you in finding any incompatible programs that are causing the problem.

• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Once you’ve found any incompatible programs, you need to uninstall them. Refer to the steps below to do so.

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Update or rollback drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Try to run the DISM tool

If the first two options didn’t work, then running the Deployment Imaging and Servicing Management might. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• 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 – Try to stop the Runtime Broker process

The RuntimeBroker.exe or the Runtime Broker process is the one that monitors access to Windows APIs to make sure that the apps do not violate the core security of Windows. This process usually leaves a very small footprint. However, there are times when it consumes more resources than it’s supposed to and does not release memory after the work is done that results in a memory leak. As a result, it affects NTOSKRNL.exe which is why you have to stop the Runtime Broker process. To do so, refer to these steps:

• Tap the Ctrl + Shift + Esc to open the Task Manager.
• After opening Task Manager, go to the Processes tab and look for the Runtime Broker process.
• Once you find it, check if it is using more than 15% of your memory. If it is, then you most likely have an issue with an app installed on your computer.
• Select the Runtime Broker process and right-click on it and then click on the End Task option to end its process.

Option 5 – Try to run the Performance Troubleshooter

• Tap the Win + R keys to open the Run dialog box.
• Type “msdt.exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
• Then click on Next to get started. Wait until the process is completed.

Option 6 – Try using the Windows Performance Toolkit

You can also use the Windows Performance Toolkit in finding the root cause of the problem. Just refer to the following steps to use this toolkit.

• Search for “cmd” in the Cortana Search box and click on Command Prompt from the search results to open it.
• Next, type in the command given below or copy and paste it and then hit Enter:

xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl

• After executing the command, wait for at least 60 seconds and then check the logs of the Windows Performance toolkit which is stored in a file named cpuusage.etl in the folder located at C:/Windows/System32. From there, you should see a list of all the causes of the System Resources being hogged.

Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:

“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”

Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.

• Extract the Windows 10 ISO files using an extractor.
• Then browse to the folder you created and go to the sources folder.
• From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:

[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Note: “xxxxx” is the KEY to your Windows version.

• Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.

Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

If you got an error message saying, “Folder Redirection Failed, Failed to build the list of regular subfolders, Access is Denied” after you configured a new Group Policy Object or GPO which redirects User folders to a new network share or when you click on Reset default location under the Windows File Explorer or Folder Options, then you’ve come to the right place as this post will show you how to resolve this kind of error on your Windows 10 computer. Follow the given options below carefully to fix the “Folder Redirection Failed” error.

Option 1 – Take Ownership of the folder

If you are not able to access the folder could be one of the reasons why you’re getting the “Folder Redirection Failed” error and so you need to take ownership of the folder to resolve the problem. Before you proceed, make sure that your account is an admin account.

• First, locate the concerned folder and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

Option 2 – Try to add Authenticated Users or Domain Computers

Make sure that the Folder Redirection group policy removal option is set to “Redirect the folder back to the user profile location when the policy is removed” when using the Folder Redirection. After that, you have to add Authenticated Users group with the “Read” permissions on the Group Policy Objects or GPOs. And if the Domain computers are part of the group of “Authenticated Users”. Note that by default, the “Authenticated Users” have these permissions on any new Group Policy Objects or GPOs. Once again, you have to add just “Read” permissions and not “Apply Group Policy” for “Authenticated Users”. Furthermore, to fix the “Failed to build the list of regular subfolders” errors, here are some options that could help.

Option a – Try to clear disk space

You might have to check if your disk is running out of space because if it is, then it will fail to create a list abruptly. And so you need to free up some disk space. You can either check on the files manually especially if you tend to keep your files at random places in your disk drive.

Option b – Find the Target route

You need to find the target route of the folder and then restore it if you are getting the “Failed to build the list of regular subdirectories” when you try to relocate the folder to the original location.

Option c – Try to change Ownership/Reset Defaults for all the User folders

If the “Failed to build the list of regular subdirectories” error pops up when you are trying to move a large number of files from one location to another, then you need to change the ownership of the folders as pointed out earlier.

Windows 11 is a good-looking operating system but people love to make things personal and to their liking so we decided to help you in this mission with small customization of changing default system fonts inside Windows 11.

Since there is no really easy way to just switch the font windows is using for itself we will have to tweak a registry a little so before we start please do make a backup of the registry file and follow the steps as they are presented in order to avoid any errors and break the system.

So, if all precautions are made and you are ready to change your Windows appearance let's dive right into it:

Find and/or install the font that you wish to use

There are vast free font sites on the internet where you can find fonts that you like and wish to use but be very careful with your desired font selection. The font that you choose needs to be a complete typeface, meaning that it has to contain all glyphs, large and small font sizes, all special characters, etc or you will experience that in certain areas nothing will be displayed.

Once you have found the font that you like and made sure it is a complete font, install it on your system (you can skip this step if you just want to change the system font with one already installed on your system)

Create REG file

Open notepad or a similar plain text editor in order to create a file that will apply changes directly into the registry and create a new file. Inside the file paste this text:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"=""
"Segoe UI Bold (TrueType)"=""
"Segoe UI Bold Italic (TrueType)"=""
"Segoe UI Italic (TrueType)"=""
"Segoe UI Light (TrueType)"=""
"Segoe UI Semibold (TrueType)"=""
"Segoe UI Symbol (TrueType)"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]

"Segoe UI"="NEW-FONT"

All the way to the bottom where it says: "Segoe UI"="NEW-FONT", change NEW-FONT with the font name that you have chosen or installed in the previous step. For example: "Segoe UI"="Ubuntu".

Now go to File > Save As and name your file however you want but give it REG extension so it looks like: my_new_windows_font.REG

Apply changes

Now that you have your registry entry saved, locate it and double-click on it, at this stage Windows warning will probably pop up, you can just ignore it and click on YES since you wrote the file and know what it is. After registry entry is applied reboot your PC in order for changes to take effect.

Rolling back

If you want to change the font to another one, just repeat this procedure again. If you want to roll back to using the default Windows font, repeat the process but with this code instead of the one provided in the REG file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"="segoeui.ttf"
"Segoe UI Black (TrueType)"="seguibl.ttf"
"Segoe UI Black Italic (TrueType)"="seguibli.ttf"
"Segoe UI Bold (TrueType)"="segoeuib.ttf"
"Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf"
"Segoe UI Emoji (TrueType)"="seguiemj.ttf"
"Segoe UI Historic (TrueType)"="seguihis.ttf"
"Segoe UI Italic (TrueType)"="segoeuii.ttf"
"Segoe UI Light (TrueType)"="segoeuil.ttf"
"Segoe UI Light Italic (TrueType)"="seguili.ttf"
"Segoe UI Semibold (TrueType)"="seguisb.ttf"
"Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf"
"Segoe UI Semilight (TrueType)"="segoeuisl.ttf"
"Segoe UI Semilight Italic (TrueType)"="seguisli.ttf"
"Segoe UI Symbol (TrueType)"="seguisym.ttf"
"Segoe MDL2 Assets (TrueType)"="segmdl2.ttf"
"Segoe Print (TrueType)"="segoepr.ttf"
"Segoe Print Bold (TrueType)"="segoeprb.ttf"
"Segoe Script (TrueType)"="segoesc.ttf"
"Segoe Script Bold (TrueType)"="segoescb.ttf"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]

"Segoe UI"=-

In Windows 11 by default inside the Start menu, there is recommended section that contains recently opened folders, documents, and files. If you do not wish this section and do not want recent items in your Start menu there is an easy way to turn it off.

1. Press ⊞ WINDOWS + I to open settings

Internal Error 2771 - What is it?

Internal Error 2771 is an internal error code associated with Kaspersky Internet Security and Antivirus software. This error pops up when Kaspersky Internet Security software fails to install on your PC successfully. Installation of the software is interrupted and therefore it ends prematurely. This happens mostly when you try to install a new build on an existing installation. Internal Error 2771 is displayed in one of the following formats:

Internal Error 2771, Sandbox Feature or Internal Error 2771, WholeProduct Feature

Solution

Error Causes

This error may result on your computer screen due to several reasons. Some of the most common underlying causes include:

• A leftover Registry Key
• Bad entries from previous Security Package
• INFCACHE.1 file corrupted
• Conflicts with other security software installed on your system

Further Information and Manual Repair

To successfully overcome this problem and ensure the successful installation of Kaspersky Internet Security software on your system, try the methods given below.

Method 1- Remove the Leftover Registry Key

Sometimes Internal error code 2771 may appear during installation due to the leftover registry key from the previous Kaspersky software removal. A registry key is often created when uninstalling the previous Kaspersky version from the PC. This key is left behind even after you reboot your system. This key is called AVP**_post_ uninstall, you need to delete it to ensure the new version of the Kaspersky program is installed successfully on your PC.  For this, simply go to the start menu and type Regedit in the search bar. Now navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun and then look here for the registry key called AVP**_post_ uninstall. In order to delete this file, right-click it and then select delete. Once uninstalled, reboot your PC and then try installing the Kaspersky Internet Security program again. Hopefully, this will resolve the issue. If the software installs smoothly, then the error is fixed, in case it still persists, then try other methods illustrated below.

Method 2 - Remove the INFCAHCE.1  Corrupt File

Another reason for the error pop-up may be INFCAHCHE.1 corruption. This file is basically used to store driver information and inf file locations. However, if it contains corrupted information, then you must remove it. To do this, go to the start menu and type cmd into the search bar. This will open a command prompt. Here type del C:\Windows\infinfcache.1. Now reboot your PC and try installing Kaspersky software on again.

Method 3 - Fix Software Conflict

Security software conflict can also result in internal error 2771 code display. And when this happens, the installation of Kaspersky prematurely ends. Security software conflict may occur if you have Comodo Firewall installed on your PC. A firewall is known to cause issues with Kaspersky software programs. The best way to resolve this issue is to uninstall all security software programs on your PC. Once all security software is removed, then install Kaspersky on your system. If the installation is successfully completed, then reinstall the other software again.

Method 4 - Download Restoro

Error 2771 can also result on your computer screen if traces of the previously installed Kaspersky software still remain in the registry despite the program removal.

A black screen error inside Windows 11 is a typical screen turning to solid black without any error message. This can be very annoying since it can randomly appear out of nowhere and it will appear while you are using the computer. Worry not, this is not a serious error and we have several solutions for it, so please keep reading and try them as presented in order.

Restart graphic driver

This is the first thing to check if the issue is due to software or driver malfunctioning, there is a shortcut for rebooting graphic driver inside Windows 11. Press WINDOWS + CTRL + SHIFT + B to reboot the graphic driver and see if this fixes the issue. A beep sound should be heard during this process and the screen should turn back to normal.

Check connections

Sometimes the screen can go black due to a faulty connection or cable. If you have it at your hand try a different cable or slightly and gently nudge the existing one to see will screen flicker. If you are on a laptop try gently moving the lid from back to front and pay attention to the screen. If screen flickers or picture returns with this method, cable or connector needs to be replaced.

Clean your computer

The black screen can be because the computer is overheating. If this is the case either fan inside is not working properly or there is a lot of dirt and dust that needs to be removed so airflow can be established again for proper cooling. We have an article on errortools.com on how to properly clean your PC but if you are not technical enough maybe the best solution would be to call someone who is or to take the PC to service for cleaning.

Change The Projection Settings

Press WINDOWS + P to open projection settings, check to see if PC is set to PC screen only. If any other option is selected change it to PC screen only since this can cause random black screen issues.

Uninstall latest updates

If this problem has started to manifest itself during the latest update, go to setting and roll back from the latest update to fix this issue.

Scan system for malware

The black screen can also be caused by various viruses and malware. IF you have anti-virus software, run a full system scan to check it for malware. If you do not have one, download a free one and run a system scan, we recommend Bitdefender.
