I also tried using the du.exe tool (technet.microsoft.com/.../bb896651.aspx) however the first time you run it there's a Terms&Conditions popup and users needs to click accept.

Most Sysinternals utilities take an -AcceptEULA switch. Alternatively, you can add the registry value directly:

reg add "HKEY_CURRENT_USER\Software\Sysinternals\Du" /v EulaAccepted /t REG_DWORD /d 0x00000001 /f

Hi,

This script will check all your domains workstations and list the size of all user profiles in a csv in c:\kworking

This client doesnt have a domain. Would it work for them?

@smason looks like that works! thanks

NB: Sloeber70's script doesn't work on non-domain machines.
