1. Find the file c:\windows\SchedLgU.txt, which contains the time from system production to work, including when to start, when to start and when to shut down!

2. Check the recently run programs:

Under C:\WINDOWS\Prefetch. There is a record of what programs have been run. The program name is at the top of the file, and the execution code behind it is ignored! If it has not been optimized, the things saved here should be very valuable!

3. See which files (non-programs) and folders have been opened recently!

Start-Run-Recently

4. Look at what you have done on the Internet recently. ...................................................................................................................................................................

Display all files in a folder, find the directory c: \ documents and settings \ xukunping \ local settings, and explore this folder slowly. If you don't clean the disk or optimize it, all the records can be in this folder.
