jerriy You didn't really solve the problem because you went from 1909 to 21H1 that's why it shows you as up to date.
I was going to suggest what you had to do for Windows to report you as up to date, but I guess it's too late now.
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
"ProductVersion"="Windows 10"
"TargetReleaseVersion"=dword:00000001
"TargetReleaseVersionInfo"="1909"
I have my "TargetReleaseVersionInfo"="1903" and I am on the final build version of 1903 up to date! Windows is reporting as up to date since 4th of December when I freshly reinstalled Windows 10 Pro 1903.
By setting the Target Release Version to the specific version, you can remain at that version forever! This is what you could've basically done and remain at 1909. But since you updated to 21H1 ofcourse Windows 10 will naturally report you as up to date.
TargetReleaseVersion fools Windows in thinking you are up to date as it only looks for updates related to that specific version of Windows. I think this is a lifesaver because without this Microsoft will force upgrades to latest version against the users will.
