Now if you do not want this license agreement to pop up for every user, you must add the registry key that accepts the license key to each users profile before the script is launched. If you are scripting in batch this can be done with:
reg.exe ADD "HKCU\Software\Sysinternals\du" /v EulaAccepted /t REG_DWORD /d 1 /f
All Sysinternals utilities are all configured the same, just replace the \du with the name of the tool such as \psexec.
I also found the a bunch of other Sysinternals applications which you can add to the registry on Peter Hahndorf's blog. This can be found on the following URL:
