Clear history of recently opened documents on exit
If you open a file Windows will automatically add it to the context menu of that program when you right-click the program at a later moment. Word is a good example of this behaivor. But if you do not want Windows to do this then disabling it through this Registry tweak is what you need
1. On your keyboard press the Windows flag and the R key at the same time (Windows +R) or open Start.
2. Now type Regedit.exe (1) and click on OK (2)Run: Regedit/caption]
3. Now Unfold HKEY_CURRENT_USERHKEY_CURRENT_USER/caption]
4. Then Unfold Software
5. Then Unfold Microsoft
6. Then Unfold Windows
7. Then Unfold CurrentVersion
8. Then Unfold Policies
9. Then Unfold Explorer
10. Now double-click on ClearRecentDocsOnExit and change the value of ClearRecentDocsOnExit to 1
If the key does not exists then right-click an empty spot and choose New then choose DWORD.
11. Click on OK and close Regedit. A reboot might be necessary for the changes to take effect upon your system.
If you wish to disable this tweak at a later moment just repeat the steps above and change the value back to the original value, which was 0. If you have any questions about this tweak, please feel free to ask them on our forums
