Hum! I've been using just:
Update-Help -forceWithout the "-Scope CurrentUser" parameter and is working fine on non-admin session.
Maybe the "-Scope" is not a mandatory parameter.:)
Never mind!! Only in Windows works OK.
In Ubuntu 18.04, I'm getting the same error too!

You can't even use "sudo" to execute "Update-Help".
This is a bug!:)
Here is the stack trace:

SetDisablePromptToUpdateHelpit always writes to the systemwide setting which are read-only in snap.This might be a good opportunity and excuse to move updatible help and profiles (which have the same problem) outside of pshome
Reacted by Bryan DadySnap allows to write to user home.
Also I guess snap allows to make any directory writable (pshome too).Please continue discussion in #9278
Reacted by Bryan DadyThe problem here is different than #9278. This cmdlet is writing the the WRONG scope even when the scope is specified. We need to fix this issue.
