Windows Start Menu and Taskbar Don't Work

Hi, on occasion when I mouse over either the start bar or the taskbar it doesn't change colour like it usually does (the little blue background it changes to for instance) and it doesn't let me click on them. As well as this, it doesn't let me click on any window that isn't the currently selected one. I've tried running SFC /scannow but it says there's no problem, as well as reinstalling windows apps with powershell.

There doesn't seem to be any noticeable way to recreate this happening reliably, it just happens completely randomly. I've found a way to fix it when it comes up, which is to run any program in administrator mode (I usually run cmd in administration mode by opening it with my keyboard and holding ctrl shift enter) and then when the message asking if I want to open it in administration mode comes up, entering yes with my keyboard. When I do this it fixes it back to normal.

Thank you for any help.

Give this a try...............................

Right click at it > click Command Prompt (Admin) > type powershell > press Enter key.
At the flashing prompt, copy and paste this command line ( to avoid typo it's best to apply Copy/paste method)......
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

> press Enter.

As I said in the opening post, I have already done that, thank you anyway.

Sorry, I don't see anywhere from your original post mentioning that you had already done that.

But, if you say so, then I apologize for repeating something you have already tried.
