    Aditya Patwardhan (@adityapatwardhan) I thought we changed the default target to be the user?

    I verified update-help -Scope CurrentUser fails as well with the same error

    Hum! I've been using just:

    Update-Help -force

    Without 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!

    BTW

    You can't even use "sudo" to execute "Update-Help".
    This is a bug!

    The problem is SetDisablePromptToUpdateHelp it 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

    Snap allows to write to user home.
    Also I guess snap allows to make any directory writable (pshome too).

    The 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.
