There are various environment variables in Windows that you might use. Both
"windir" and "SystemRoot" point to the Windows OS's directory, typically
C:\WINDOWS. I don't recall if "SystemRoot" was there all along, but "windir"
was there since the early days of Windows; indeed, it was spelled with lower
case letters so that the DOS SET command couldn't manipulate it. There's
also "ProgramFiles", which typically refers to "C:\Program Files". Not sure
if it's possible to configure Windows to put this on a different drive from
the OS, but some Googling might come up with some more info on this.
