There are some users who‘ve updated to find that the installed version isn’t what they expected after a clean install - they have Enterprise version installed but chose Pro, even a few Home users have found that Pro installed for them & not Home.
That’s the first thing to check.
If this shows the correct version then check to see if the license is valid:
Run this to see what is currently installed & post the screenshot:
Right click on start & choose powershell with admin & enter: slmgr.vbs /dlv
This will show a popup showing whether your license is OEM, Retail, or Volume amongst other information.
