How to fix the Start Menu on Windows 10 (Pin/Unpin)

So you don’t like the taskbar much and you decided to pin your Turbine launcher on the Start Menu of your newly installed Windows 10 rig, together with a number of nice music apps to play with, work-related apps, news apps and more… and suddenly trying to pin or unpin an app doesn’t seem to change anything…

It happens on some systems (happened to one of my three PCs) and it’s one of Windows 10’s little quirks from last year that they still need to iron out – but fear not: there are solutions. :)

Before we look at the solutions, you should not keep pinning and unpinning apps on the Start Menu to try and see if that will work because it actually does work and it will keep pinning and unpinning whatever you did; it’s just that once this bug hits then simply you can’t see the results of this happening because of the bug; but it continues to happen. :)

So here is what to do if you face this problem.

The first thing to try (as always) is Restart your PC and see if that fixes the issue.

The second thing to try is to reshuffle your pinned apps around a bit. Sometimes the continuous ‘refreshing’ that occurs because of reshuffling fixes the problem.

If neither of these two methods work, then there is something else to do. But first, backup any data you’ve saved in the Modern Apps as all of them will be re-installed. Desktop software and apps won’t be affected though.

So the third thing to try is this:

Open Windows PowerShell as Administrator as follows:

Right-click the Start button. Choose Command prompt (Admin). Key in Powershell in the black window and hit Enter. Paste the following command in the Administrator: Windows PowerShell window and press the Enter key:

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

Wait for PowerShell to execute and complete the command. Ignore the few errors (in red colour) that will pop up. When it finishes, try hitting Start. You should now see whatever you pinned and unpinned before having appeared on or disappeared from the ‘Pin Section’ of the Start Menu.

To test if all is fine, try to pin a new app and then to unpin it, to make sure it works fine. 

Edit 4/2/2016: While this does work, I wouldn't mess around with the Start Menu for now as it's the most bugged part of Windows 10...
