Steps to reproduce
help Compress-Archive -ShowWindow
#works with any command, not just Compress-Archive
Expected behavior
help Compress-Archive -ShowWindow
#expect a new window to pop up displaying the help for the cmdlet.
#Since this is really a Windows platform thing, then it would be ok if this parameter simply was not there
Actual behavior
PS C:\Program Files\PowerShell\6> help Compress-Archive -ShowWindow
Get-Help : A parameter cannot be found that matches parameter name 'ShowWindow'.
