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.

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.

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.

If you are checking for an update on your Windows 10 PC and you got the error 0x80070005 due to some ACCESS DENIED permissions issue, then read on as this post will show you what you can do to fix the problem. For some reason, the Windows Update does not have enough rights or permissions to continue further which is why you’re getting an error instead. Thus, the first thing you can do before you troubleshoot further is to make sure that you’re logged in as admin. However, if you’re already logged in as one, then here are some suggestions that might help you fix the Windows Update Install Error 0x80070005.

Option 1 – Restart your computer and try installing the Updates again

You can restart your computer and then try installing the updates once again. There are instances when a simple restart resolves Windows Update errors. Thus, after you restart your computer, check for updates once again and see if you’re still getting the error or not.

Option 2 – Delete the contents in the Software Distribution folder and Catroot2 folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 3 – Try running the Windows Update Troubleshooter

After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Take control of the User App Data

There are times when permission to access the files is not configured correctly. As a result, it blocks the downloading of the updates. Thus, you have to take full control of the User App Data which is placed at C:/Users/USERNAME/AppData.

• First, go to C:/Users/USERNAME/AppData 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 5 – Try to update Windows after a couple of minutes or an hour

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it a couple of minutes or an hour or so before trying to run Windows Update again.
