[Fix] Unresponsive Taskbar in Windows 10

Some users of Windows 10 report an unresponsive taskbar. This problem has dogged beta-versions of Windows 10 since around February 2015 and Windows doesn't seem to be able to remedy the problem. 

So, your taskbar doesn't seem to react to your mouse clicks or left clicks, but it does react to right clicks. When hovering over taskbar icons, tooltips do not seem to work properly. 

The fix is relatively easy. 

[1] Right click the Start button
[2] Choose Command prompt (Admin)
[3] Type 'PowerShell' (without the '') in the black window (C:\WINDOWS\system32>PowerShell) and hit Enter
[4] Paste the following command in the Administrator: Windows PowerShell window and hit Enter:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

[5] Wait for PowerShell to execute and complete the command. Ignore the few errors (in red color) that may pop up.

Now your taskbar should – hopefully – be back to normal (again).
