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.

Why you should upgrade your 60Hz Screen

The number of Hertz is the number of how many images your screen draws in one second. So monitor with a refresh rate of 60Hz will draw 60 images each second on your screen. To most users, this will look fine and enough but actually, if you would place them in front of a 120Hz screen difference will be visible right away.

high refresh rate monitor setup

Benefits of higher refresh rates

In most simple words just looking at a screen that has a higher refresh rate will produce a more natural feel of things, although some people would argue that flickering can not be seen on 60Hz monitors and that should be enough, I would argue that they never watched the movie, played the game or used high refresh rate screen when they can state something like that.

Yes, 60Hz might be enough to look at the web page or read some documents but long exposure to 60Hz can have a tiring effect on the eyes in the long run. 120Hz and above just feel more relaxed and it is far less demanding on the eyes. Watching movies also is much better on a higher refresh screen, with way much less motion blur in fast scenes giving the overall experience a greater natural feel.

Gaming is perhaps an area where a refresh rate of 120Hz and above will show its best. Having a higher refresh rate will be easier on your eyes and can even give you a competitive edge. When for example you have twice more images per second on your screen than your opponent his movement will be more fluid and predictable because of that and overall precision will be much higher when moving the cursor in the game since more frames per second means more precision and smoother movement.

The dark side of high refresh rates

After all the positive things that were said about the advantages of high refresh rates, it is just fair to look at some negatives or in this case only negative one and that is Computer power. As said in the previous section having a 120Hz refresh rate means having 120 frames displayed on the screen per single second. Having even higher monitors like 360Hz means even more frames per second and in order to actually see all of that frames you will need to have enough computer power to back it up. Having for example screen with a refresh rate of 240Hz means nothing if your GPU and rest of the computer are able only to push 150 frames per second, in this case, you will still have 150 frames in one second despite the monitor being able to go to 240.

Conclusion

Generally and with all of my heart I would recommend moving away from 60Hz monitors, yes they are cheaper and more affordable but at the end of the day if you are someone like me who spends most of his daily time in front of the computer you would be grateful to have higher refresh rate screen and save your eyes, and after all, why not enjoy some smoother and better movie and game experience as well as saving your eyesight.

After that, refer to the following instructions. Step 1: First, in the Start Search, type “command prompt” in the field and from the search results, right-click on Command Prompt and then select the “Run as administrator” option to open Command Prompt with admin privileges. Step 2: After opening Command Prompt as admin, navigate to the folder where the file you want to delete is located. Note that you have to execute the “cd” or the change directory command. Step 3: Next, execute the following command in Command Prompt:
DEL /F /A <file path with extension>

Windows 10 is stuck on Checking for updates
Over the years, the Windows 10 updates have smoothened but that does not mean that it no longer encounter some issues. One of these issues is when it gets stuck. As you know, Windows automatically checking for updates regularly or when you click the “Check for updates” button. However, if the Windows 10 update is taking forever and seems to be stuck, then you’ve come to the right place as this post will guide you on what you can do to resolve the problem. This kind of scenario in Windows Updates can be quite confusing especially since there is no response or any indication of what is really happening since you don’t know if the update is still downloading or if it’s already getting installed. To resolve this problem, there are several options you can check out. You can try to exit settings and restart your computer. You could also try to restart the services related to Windows Update or clear both the Software Distribution and Catroot2 folders, as well as run a System File Checker scan. For more details follow each one of the given steps below.

Option 1 – Restart your computer

The most basic thing you can do to fix the problem is to restart your computer. It usually works in fixing common issues like the Windows Update getting stuck at the “Checking for updates” screen. However, if it didn’t work, proceed to the next given options below.

Option 2 – Reset Windows Update components

If the first two options did not work then you might want to reset the Windows Update components manually. Follow the steps below to reset them.
  • Open Command Prompt with admin privileges.
  • After that, type each one of the following commands and hit Enter after you key in one after the other.
    • net stop wuauserv
    • net stop cryptsvc
    • net stop bits
    • net stop msiserver
Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.
  • After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
    • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
    • ren C:WindowsSystem32catroot2 Catroot2.old
  • Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
    • net start wuauserv
    • net start cryptsvc
    • net start bits
    • net start msiserver
  • Close Command Prompt and reboot your PC.

Option 3 – Try checking Services Dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependent service will also be affected. This could be the reason why the Windows Update service could not start.
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “services.msc” in the field and hit Enter to open Windows Services.
  • From the list of Services, look for the following services:
    • Remote Procedure Call (RPC) Service
    • DCOM Server Process Launcher
    • RPC Endpoint Mapper
  • After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
  • If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Option 4 – Check the Background Intelligent Service and the Cryptographic Service

  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “services.msc” in the field and hit Enter or click OK to open Services.
  • From the list of Services, look for the following services and make sure that their Startup type is as follows:
    • Background Intelligent Transfer Service – Manual
    • Cryptographic Service ­– Automatic
  • After that, check if the Service status of the listed services above is set to Running. If they’re not, click on the Start button to start these services and then check if you can now enable the Windows Update service or not.

Option 5 – Try running 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 your screen is stuck at “Checking for updates”. 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.
  • Restart your computer.

Blue Screen of Death in Windows

Symptoms of Blue Screen of Death Errors

Symptoms of a blue screen of death problem are easy to identify: if you have a blue screen error, then your computer will display a blue screen. Also known as the infamous “Blue Screen of Death”, this screen will pop up when something goes horribly wrong with your computer. The screen displays cryptic information about the problem before automatically restarting the system.

Restoro box imageBluescreen Error Causes

This one can be a bit more complex: blue screens are caused by hundreds of different things. In fact, any miscommunication between the hardware and software of the computer can lead to the dreaded Blue Screen of Death, blue screens reference a communication problem between the Windows operating system and the hardware in your PC.

Why do computer blue screens of death errors occur?

Most computer users have experienced a blue screen of death at least once in their life. But have you ever stopped to wonder why they occur? Blue screens of death can occur for a number of different reasons, but the most common reason is that your PC’s hardware failed to properly communicate with its software, resulting in a fatal error. If your video card, processor, hard drive, or any other vital system component encountered a serious communication error with your operating system, then your PC may automatically display the blue screen and shut down for its own safety. Blue screens can also occur as a self-protection mechanism if the PC is overheated.

Further Information and Manual Repair

Where do Windows blue screen errors come from?

Blue screen errors come from many different sources on your computer. However, the majority of blue screen errors seem to come from the Windows Registry, which contains important configuration information about the programs, data, and personal files on your PC. Windows constantly rely on the registry in order to operate normally, but since the registry is incredibly complex (it holds hundreds of thousands of files), errors naturally develop over time. Fortunately, registry errors are fixable. They can be repaired using special registry cleaning software. During a scan, registry cleaning software looks for any registry entries that have errors. Once these entries are found, the software automatically repairs each entry. In many cases, this can permanently repair the blue screen error and prevent blue screens from ever appearing again.

Blue screen Windows 7

Windows 7, despite being Microsoft’s most popular operating system to date, is not immune to blue screen errors. It’s more stable than previous versions of Windows, although many users will inevitably encounter blue screen errors in Windows 7. No matter which version of Windows you’re currently using, the error remains the same: the hardware on your computer has trouble communicating with the software, forcing the system to display the blue error message we all love to hate.

“Blue Screen of Death”

There’s a reason this error message is famously called the “blue screen of death.” Immediately after displaying a blue screen, the Windows computer will ‘die’, which means that it restarts itself. Another reason why the error could be called the blue screen of death is that it is often displayed at the end of a PC’s life cycle. As PCs get older and their hardware starts to fail, blue screen errors become more and more common. In real life, death isn’t reversible. In the computer world, blue screens of death certainly are. With the right software support – like Restoro – even the most novice computer technician can fix their blue screen errors and restore their PC to healthy working conditions.

What to do if the Windows Wireless Service in Windows 10 is not running
When experiencing internet connection problems, most users run the built-in troubleshooter to fix the problem. However, you might come across another problem when instead of fixing the problem, the troubleshooter throws up an error message saying, “The Windows Wireless Service is not running on this computer”. After displaying this error message, the troubleshooter would exit. Usually, this kind of error indicates that Windows has failed to initialize the wireless service so it can start searching for broadcast signals and try to connect to them. So in this post, we have prepared some workarounds that might help you resolve the issue.

Option 1 – Try to check the WLAN Status

You have to make sure that the wireless service is enabled in your computer before you proceed to the other troubleshooting options below as this error could occur for a simple reason as the wireless capability is turned off from your PC either on some built-in settings or physically. This is why you need to make sure that Wireless is enabled. And if it turns out that it is disabled, you need to turn it back on and then reconnect to the wireless network again. You should now be able to connect to the internet without any issue.

Option 2 – Try to check the WLAN AutoConfig Service

The WLAN AutoConfig service is the one that provides the logic and functionality required to discover, connect and configure wireless networks with your PC. Aside from that, it also contains the module that allows your PC to be discoverable to other systems on a network. Thus, you need to verify if the WLAN AutoConfig service is on or not.
  • Tap the Win + R keys to open the Run dialog box.
  • And in the field, type in “services.msc” and hit Enter to open Services.
  • After opening the Services window, look for the entry named “WLAN AutoConfig” and then right-click on it and select Properties from the context menu.
  • Next, click on the Start button to turn on the service and then set the startup type as “Automatic”.
  • Then try to connect to your Wireless network again and check if the issue has been resolved.

Option 3 – Try to reset the Network Configurations

Resetting the Network Configurations can also help you in fixing the Windows Wireless service as the network settings often get disrupted or corrupted in a variety of different cases every now and then. Note that this module will reset all the network settings stored on your computer.
  • Tap the Win + S keys to open Search and then type in “command prompt” in the field.
  • From the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
  • After opening Command Prompt, copy and paste the following command and hit Enter to execute it:
netsh winsock reset
  • The command given will reset the Winsock data. Once it is executed, restart your PC for the changes to take effect and then check if the internet connection is now fine.
Note: Do make sure that the WiFi drivers are up to date. To do that, follow these steps:
  • Tap the Win + R keys to launch Run.
  • Type in devmgmt.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. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
  • Restart your PC.
Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it.

Option 4 – Perform System Restore

Recently, a lot of issues have resurfaced after users installed the latest Windows update. So the wireless service issue might also be related to it. To fix the problem, you can perform System Restore to roll back your Windows to the last time when it was working just fine. It automatically creates backups in time whenever you install a new update or periodically. Follow the steps below to perform System Restore.
  • Tap the Win + S keys to open Search and then type in “restore” in the field and select the topmost result.
  • Once you’ve opened the restore settings, click on System Restore located at the beginning of the window under the System Protection tab.
  • After that, a wizard will appear that will guide you through all the steps needed to restore the system. You can choose either the recommended restore point or a different one.
  • After you select the restore point, click Next to proceed to the next on-screen instructions.
  • Then select the restore point where the Windows Update was installed on your computer. If you have more than one restore point, you can just select the latest restore point and check the functionality from there. If it doesn’t work, you can just try another restore point.
  • Another prompt will appear and will ask you to confirm your actions. Click OK and wait for the system to be restored. Once it’s done, check if the problem’s now fixed.
