Here's a 4-1/2 minute video by Keith Combs showing a great new feature in Windows 7, the Problem Steps Recorder, or PSR.
PSR allows end users to record the actions they took to produce a problem.
The user enters PSR in the start menu, clicks Record, and then performs the steps to produce the problem. When the user clicks Stop Record, they can optionally enter comments and save the recording to a single ZIP file. Then they email it to the support staff.
The ZIP file contains an MHT file with screen shots and written actions that documents everything the user typed or clicked during the recording session.
This will be very useful for help desk and support staff in corporate environments, not to mention all those calls I get from my parents.
