This program can do a billion useful things for annoying MS OS users. Click Start > Run and then type in msconfig and hit enter.

1. You can change to selective startup and disable your startup items, which is useful for troubleshooting.

2. Click the Advanced button. Check Disable Scandisk After Bad Shutdown. Now when you get GPFs or BSODs, you won't have to press enter to make scandisk go away when you reboot!

3. Also under the Advanced button is an option to make the Windows Startup Menu automatticly appear when you start your computer, letting you select from Normal or Safe Mode (as opposed to having to hold F8 or Ctrl to make it come up).

4. Also under Advanced, you can specify how much memory you want the system to use. When my second block of 64MB of RAM went bad, I bumped this down to 64MB (I have two 64MB chips) so that I would stop getting General Protection Faults. Really nifty.
