To find out which users have a (local) user profile on your machine, and where this profile is located, try this snippet:
$path = 'Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\*' Get-ItemProperty -Path $path | Select-Object -Property PSChildName, ProfileImagePath
It will automatically enumerate all keys below ProfileList, and return the user SID and the path to the profile:
PSChildName ProfileImagePath ----------- ---------------- S-1-5-18 C:\WINDOWS\system32\config\systemprofile S-1-5-19 C:\Windows\ServiceProfiles\LocalService S-1-5-20 C:\Windows\ServiceProfiles\NetworkSer...
