Thanks for the reply.

psexec.exe runs under my user account from the command line. I can
control which user runs notepad.exe from the command line using the -s
flag for System, or I can specify a different user with the -u and -p flags.

psexec.exe runs as System from PHP.

It makes me wonder if this is related to access privileges, but I don't
know what the correct settings are. Do all the executables have to be in
the same directory? Do I have to configure PHP with certain access
privileges? I'm not very skilled with these settings on Windows.
