I want to map a folder to a drive at startup. I did this on my Windows XP box by adding a registry entry in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run, which said:
subst v: c:\vss
This doesn't work in Windows 7, i.e. whenever I boot the subst'd drive is missing. I'm not running as admin on this 7 box whereas I was on the XP version.
