TekTip ep3 - The Sticky Keys Trick

In this episode of TekTip we take a break from Malware Analysis and play with an old sys admin trick commonly known as the Sticky Keys trick.  I cannot tell you how many times I have used this to log into lockedout machines from family, friends, co-workers, and clients.  This will work on XP, server 2003, Vista, Windows 7, and probably the rest of them as well.  A quick summarry of the steps involved are:

1. Boot to a live linux distro (BT5 will work fine)
2. Mount the windows drive 
3. Replace sethc.exe with cmd.exe
4. Reboot to Windows
5. Press shift 5 times to bring up command prompt.
6. Command prompt aquired, mission accomplished.
