1. Overview.

In Windows XP, the task scheduler service runs as "SYSTEM" (local service);
this is akin to running cron as root. Any processes spawned by the
task scheduler
inherit "SYSTEM" permissions. Using command line tools, we can kill the Windows
desktop (explorer.exe) and restart it running under "SYSTEM". Once running under
"SYSTEM" we have full control of the machine, and can do things even
Administrators
can't. Also included is a recommended fix. Read the full paper at the
link below.
