Would you want to restore the backup Master File Table instead from when the computer was last used?
So you recover all files/directories that were deleted since last startup. Doesn't it create a backup MFT sometime?
I ran the Disk Cleaner in Windows Vista after CCleaner 2.02 as a standard user and it didn't clean out items such as
- Offline Web Pages
- Temporary Files
- Temporary Internet Files
- System Archived Windows Error Reporting
