All the files you open will be stored in your user profile in a hidden folder named My Recent Documents. This is really annoying and a treat to our privacy! We can make this folder auto cleared on logoff using a single registry change.

1. Click Start > Run > Type in regedit

2. In the Registry editor navigate to the following key.

Quote:
HKEY_Current_User > Software > Microsoft > Windows > CurrentVersion > Policies > Explorer
3. Right click on the Right Pane > New > Dword Value & name it as ClearRecentDocsOnExit .

4. Double Clcik on it & se the value to 1 .

This will clear the My Recent Documents Folder automatically on logoff.

To Revert back either delete the Dword value or set the value to 0.
