I just recorded a SasLibEx Screencast, it shows some of the very powerfull features of SasLibEx.

The following features are shown:

• Simulate Ctrl Alt Del (Secure Attention Sequence)
• Cancel Ctrl Alt Del
• Lock Workstation
• Unlock Workstation (without credentials)
• Disable Ctrl Alt Del
• Enable Ctrl Alt Del again
• Cancel pending UAC request
• Is Desktop Locked
