What to do if you cannot switch between Programs on Taskbar in Windows 10
It is common to run multiple programs and applications at the same time and it’s important to be able to switch between them using their Taskbar icons or using the usual Alt + Tab shortcut. However, there are times when you might suddenly find that neither of the aforementioned methods worked and you will no longer be able to switch between programs in the Windows Taskbar. To fix this issue, refer to the options given in this post. For instance, when you have multiple instances of Microsoft Edge running and every time you press the Alt + Tab combo nothing happens so you are left with no choice but to minimize everything and then hover your mouse on the icon and switch between the instances of Edge. You will also notice that the right-click on the taskbar won’t respond back and will only keep on showing the loading circle icon. Here are a few tips you can follow to fix the issue with the Windows 10 Taskbar.

Option 1 – Try to restart the Windows Explorer

This is one of the basic things you can try as restarting Windows Explorer helps in refreshing the user interface and makes most of the things work in relation to the user interface.
  • To get started, tap the Alt + Ctrl + Del keys to pull up the Windows Task Manager.
  • After opening Task Manager, look for “explorer.exe” under the list of programs.
  • Once you find the explorer.exe, right-click on it and click Restart.

Option 2 – Try changing the Foreground Lock Time

Aside from restarting Windows Explorer, you could also try changing the Foreground Lock Time to fix the issue with the Taskbar.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type in regedit in the field and tap Enter to open the Registry Editor.
  • Next, go to this registry key – HKEY_CURRENT_USERControl PanelDesktop
  • Next, change the ForegroundLockTimeout value from200000 to 0. After that, it will make sure that no other application will take away the focus from your current program or application. It could be that some other application has taken away the focus and even when you try to actually switch, the focus gets back to the old one. Anyhow, since you already changed the value of ForegroundLockTimeout, it will ensure that the focus is not switched.
Note: If you are running some Full-Screen applications there are some devices especially the gaming ones, disable the Windows key to make sure that you won’t be able to switch. If this is the case, you need to make some modifications to the Full-Screen games.

Step 5: After that, double click on the newly created DWORd to modify its value. Put “1” as its value data. Step 6: Then click OK and close the Registry Editor. Step 7: Now restart your computer to successfully apply the changes made.

Fix BlueTooth issues in Windows 10
Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.
  1. Check if BlueTooth is ON

    Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.
  2. Restart the BlueTooth device.

    Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.
  3. Check power supply

    If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.
  4. Restart PC

    Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.
  5. Checks BlueTooth device distance from computer or interference from obstacles

    The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.
  6. Reinstall or update device drivers.

    Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.
  7. Remove and Pair deice again

    if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.
  8. Use Windows troubleshooter

    If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.
If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

Fix Windows was unable to repair the drive
If you connected your Hard Disk, USB, or SD card to your Windows 10 computer and you suddenly encounter an error that says, “Windows was unable to repair the drive”, read on as this post will help you fix the problem. This kind of error indicates that the file system on the drive has become corrupted and that ChkDsk was not able to repair the problem. You can also encounter this error when you try to run the ChkDsk utility to repair the system. This kind of error is most likely due to the general corruption of the contents in the drive. It is also possible that you removed the external drive without using the “Safely remove hardware” option or it could be that the drive is still in use. To fix the problem, the obvious thing to do is to safely remove the external drive by using the “Safely remove hardware” option. If it didn’t work, you can try to run the CHKDSK utility from the command line or you could also restart your computer in a Clean Boot State and then run the scan. Before you proceed with the potential fixes provided below, make sure that you create a system restore point first or you could also create a backup copy of the data to an external drive.

Option 1 – Run the CHKDSK utility from the command line

Although some users reported getting the “Windows was unable to repair the drive” when they run a CHKDSK scan, other users reported that running it also fixed the error. Thus, you can try to run it and see if it works or not.
  • In the Windows Search box, type “command prompt” and from the search results, right-click on Command Prompt and select “Run as administrator”.
  • After opening Command Prompt, type this command and tap Enter: chkdsk <Partition Letter>: /f
  • The command you entered will start to check for errors and fix them automatically. Else, it will throw an error message saying, “Chkdsk cannot run because the volume is in use by another process. Would you like the schedule this volume to be checked the next time the system restarts? (Y/N)”.
  • Tap the Y key to schedule Disk Check the next time your computer restarts.

Option 2 – Restart your computer in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that triggers the “Windows was unable to repair the drive” error to appear when you connect your external drive or run the CHKDSK utility. 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” 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.)
  • Once your computer has restarted in a Clean Boot State, perform your scan again and see if it now works, and then start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.
