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.

As you know, the Windows Update process takes compatibility seriously. The Windows Updates need to be compatible with the hardware as well as all the installed applications in the computer else the Windows Updates will only get stuck in the process. Two of the Windows 10 errors that shows up during this case is the error 0xC1900208, 0x4000C. These error codes are caused by incompatible applications which means that there might be an incompatible app installed in your computer that’s blocking the upgrade process and prevents it from finishing. That’s why you need to make sure that all the applications on your computer are updated to their latest versions and then check the compatibility. So if there are any incompatible apps, be sure to uninstall them and then try doing the upgrade once again. Take note that these error codes are just among many compatibility issues that the Windows Update throws up. Since the error is caused by a compatibility issue, you have three options – first, you can update the incompatible application to the latest version, second, uninstall the application or trick Windows and make it seem like it’s compatible.

Option 1 – Try updating the application or software

As mentioned, you can try updating the concerned application or software to its latest version to resolve the compatibility issue and in turn, fix the errors 0xC1900208 – 0x4000C. Note that depending on where you had installed the application, your steps will change. So if you have it installed directly from the website, refer to these steps:

• Look for the built-in option to check the updates since the most application has this option.
• You also have the option to go to the website of the application and check if there is a new version available. If there is, download and update the app.

On the other hand, if you have downloaded the app from the Microsoft Store, here’s what you have to do:

• Open the Store and click on the three dots located at the top-right of the window.
• Next, click the Download and Updates option.
• From there, check if there is an update available for the store. If there is, update it.

Option 2 – Try to uninstall the application or software

If updating the app or software to its latest version didn’t help and you’re still getting the error 0xC1900208 – 0x4000C every time you attempt to install the Windows Updates, you may have to uninstall it. You will need to use the usual Program and Features to uninstall it if you have downloaded it from the website.

• 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 3 – Try bypassing the Upgrade Advisor

There are times when a software developer fails to pass the compatibility test for their apps. It could be that they work on Windows 10 upgraded version but just didn’t pass the compatibility check. So if you are pretty certain that the app really works on Windows 10, you can just bypass the Upgrade Advisor.

Windows has tendencies to remember WIFI passwords so it can reconnect automatically to them. But from time to time we change passwords and Windows does not let us change it since he has network remembered. In this case, we will not be able to connect to the internet. In this helpful guide, we will let you know which steps you will need to take in order to solve this issue and to be able to connect to the internet again.

1. Restart Modem

   First thing first, restart your modem. Windows might see it as a new network and offer you to type in the password for it.

If you got the FAULTY_HARDWARE_CORRUPTED_PAGE Blue Screen error on your Windows 10 computer then it is most likely caused by various factors. It could be caused by an incomplete installation or uninstallation of some applications or program, or it could also be caused by some exploit that intervenes with the normal functioning of the computer, as well as bad sectors on the hard disk, damaged system files, malfunctioned system drivers, modified Windows Registry files, or a Blue Screen occurrence during a Windows Update and many more. Getting this bug check means that a single-bit error was found on this page. It also indicates that this is a hardware memory error and to resolve it, you need to follow the suggestions laid out below but before that, it is recommended for you to create a System Restore Point first so that if anything goes wrong, you can always go back to the previous state.

Option 1 – Run a Memory Check to test RAM

Since the problem might have something to do with hardware memory, you need to test RAM by running a Memory Check using the Windows Memory Diagnostic. Refer to these steps to do so.

• Tap the Win + R keys to open the Run dialog box.
• Then type “mdsched.exe” in the field and hit Enter to open the Windows Memory Diagnostic.
• After that, the Windows Memory Diagnostic will give out two options such as:

1. Restart now and check for problems (recommended)
2. Check for problems the next time I start my computer

• Select any of the given options. After that, your computer will restart and check for memory-based issues upon the restart. If there are any issues, it will automatically them.

Option 2 – 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 with good system files that might be the cause why you’re getting the FAULTY_HARDWARE_CORRUPTED_PAGE Blue Screen error. 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 3 – Check for conflicting or incompatible programs by putting your PC in a Clean Boot state

As mentioned, the FAULTY_HARDWARE_CORRUPTED_PAGE Blue Screen error might be caused by some problematic programs that clash with your existing operating system. Several users reported that numerous programs that are supposedly designed to enhance computer performance are causing conflict in the system instead. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• 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” checkbox 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” checkbox.

• 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.

Option 4 – Update or rollback drivers

If the first few options 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.

Repair Error 1628

What Is Installation Error 1628?

Installation Error 1628 is, as the name suggests, an installation error. When it occurs, a generic 1628 message is displayed to the user. When this message appears, it is either a problem with the install files or an issue with the InstallShield.

Solution

Error Causes

Installation Error 1628 is caused because every Windows-based program or application has been designed that such that it has to be installed on the computer for use. This installation process is important because it not only moves files to the appropriate location on one’s hard drive but also because the process creates registry entries in Windows System files. A vast majority of these programs and applications have a built-in tool that’s responsible for aptly performing this installation. This built-in tool is the InstallShield. This establishes that when this error occurs, it is either because of some unforeseen issue that occurred during the installation process or because of some problem with the InstallShield.

Further Information and Manual Repair

In order to keep this error from occurring in the future, some recommendations are outlined below.

• Check the installation disc and determine if there are any smudges, scratches, or fingerprints on it. If the system is unable to read data from the disc, Installation Error 1628 will be generated. In order to ensure that the Installation Disc is clean, use a microfiber cloth. Dampen it lightly with water and clean the disc. Wipe the inside of the disc lightly in an outward direction, making sure that it is not wiped in a circular pattern. Try to reinstall the application or program after cleaning the disc. The issue should be resolved. However, if it persists, some problems may be with the InstallShield.
• The alternative solution is to repair the InstallShield and the procedure goes as follows.

1. Stop InstallShield’s running process. It may have been crashed and simply needs to be restarted. Now access task manager. Press Ctrl+Alt+Del and the task manager will open. Now go to the processes tab and disable ‘idriver.exe’ and ‘msiexec.exe’ from here.
2. Now go to ‘C: Program Files/Common Files’. Here you will find the ‘InstallShield’ folder. Select ‘rename’ and modify the folder name to ‘InstallShield1’. Confirm rename and start the installation process again. Now Windows will try to re-install any InstallShield files one needs.
3. If the error persists after renaming the InstallShield folder, download the Windows Installer from Microsoft’s website. This file will determine whether or not your version is valid. Old versions often have bugs that cause problems. Your system is now ready to be used.

After you fresh install Windows 10 on your computer, it allows you to set up a PIN just before you can start using it. However, a number of users reported that the Windows 10 installation gets stuck on the “Set up a Pin” phase. If you are one of the users who experience the same thing, then read on as this post will walk you through fixing the problem. As users start to use their newly installed Windows 10 computer, they reported that the screen is still stuck even after they enter the correct PIN twice and there is no way for them to go forward or backward. Note that this is a part of the account setup and that your computer must stay connected to your internet connection before you finalize everything. And even though the PIN works when the computer is offline, the account setup still needs an internet connection, at least for a fresh installation. The solution for this kind of issue is quite easy and there won’t be any problem even if your computer shuts down or restarts since the installation is already complete and all that’s left is the account setup. To fix this problem, follow the steps given below. Step 1: The first thing you have to do is to turn off your internet connection or disable all connectivity from your computer. Note: If you are using either an Ethernet cable or a Wi-Fi switch to connect to the internet, you have to disable or remove them. But if you don’t have any options, just completely turn off your internet connection. Step 2: The next thing you have to do is to force your computer to shut down and then restart your computer. The setup process will eventually pick up exactly where it left off. The only difference is that there is no connection to the internet and your screen will no longer be stuck on the PIN setup screen so you now have the option to skip it and wait until you’re logged in for the first time. Step 3: Once you’re done, you can then you can choose to Setup Pin later on and turn your internet connection back on or connect your computer with an internet connection.

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer.
