Upgrading Windows 11 ARM from 22h2 or 23h2

I run Windows 11 on ARM in Parallels on a Mac Studio for testing.

Windows Update would say up to date but needed to move to the next version of Windows (I was on 22h2 from initial Parallels download). I wasn’t offered the option to upgrade to the latest versions.

Solution from various sources:

22h2 -> 23h2

You can use an entitlement to enable the update the quickest.

Download: Enablement Package

23h2 -> 24h2

Create a new registry key (folder) called Windowsupdate at:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

Then create 3 values within

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Windowsupdate:

Name	Type	Value
ProductVersion	String	Windows 11
TargetReleaseVersionInfo	String	24H2
TargetReleaseVersion	DWORD	1

Once you check for updates a 24h2 download will start and install.
