What is happening with this new install I have done???

On a Dell workstation I have installed Windows 11 Pro and activated it fine from a completely new install but there are some glaring issues straight away.

Firstly the services for Windows defender all appear to be missing:

Which looks to me like it has been deleted from HKEY local machine>system control set>services so that the data cannot be recovered from the registry

Then the Defender pages say that everything is fine except that the virus status is unknown???

Presumably this is because the services have been deleted, but how did this happen?



 

OK so after trying:

• Open powershell by typing powershell into the search box on the start bar and right clicking and selecting "Run as Administrator" and then "Yes" on the following prompt.
• Then enter the following commands separately into powershell in the order shown:
• Enter: Set-ExecutionPolicy Unrestricted (Type "y" after the text prompt)
• Enter: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
• Once complete, revert the execution policy by entering: Set-ExecutionPolicy Restricted

But nothing has changed, trying a restart....
