Windows 10: Start Menu no longer working 20H2

I updated my windows 10 Pro to version 20H2 this morning and now my start menu is no longer working.
I have tried other accounts on the PC and they appear to be working fine, so it's just affecting my main account.

Anyone experienced this or have a fix?

Many thanks

:)

 

Start menu no longer works

Hi,

Thank you for posting your query in Microsoft Community.

I am sorry to know that the Start menu is not working.

Initially, I suggest you to run Windows Update troubleshooter to fix the problem.

Follow the below steps:

• Press Windows + X and select
  Control panel.
• In the search box, type troubleshooter,
  and then click Troubleshooting.

Under System and Security, click Fix problems with Windows Updates.

Please refer to the suggestions given by Sharath Srinivasa replied on January 23, 2015 in the link given below.

I Hope this information helps. Please post us if you need any help with Windows.

 

Windows 20H2 Domain Join breaks Start Menu

Upon doing a recovery of a system to start with a clean slate, it now installs 20H2. All looks good. Start menu and taskbar look normal.

We then join it to our domain. Upon reboot, the start menu will not show the applications list. No option to expose it. Start menu settings shows "Show app list in start menu" greyed out. Trying to log out shows as the only option "Change Account Settings"
Right clicking on taskbar, the task manager is greyed out. We checked the GPO for the start menu app list removal and it is listed as "not configured". Tried setting the local policy to different settings with no effect.

Read thru the event viewer and nothing jumped out as related.

All very strange. We are a hospital that has been running this AD schema for a number of years. It is based on Windows Server 2012 R2. We have over 250 systems with multiple levels of windows 10 Pro systems in production, with none of them showing these
behaviors. At this point, 20H2 is unusable for us.

 

Start menu not working

I found the following article, ran the suggested powershell command and my start menu is working again. Here it is as I found it:
Go to Start menu button and right click on it. This will open the contextual menu, after which you need to select Command Prompt (Admin). Once Command Prompt is open, go ahead with the following steps.

• Type and enter: Powershell
• Type the following: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
