PsExec gets stuck on licence prompt when running non-interactively
Use the /accepteula command-line switch to accept the licence agreement. Or set HKCU\Software\Sysinternals\PsExec\EulaAccepted to 1 Caution: if the reg key above is set to 0 (EULA was declined once) then the /accepteula will not work, you have to set the key to 1 manually (or delete it altogether).
