Clear my Recently Run list

If you frequently use the Run command in Windows XP (Start->Run), chances are you probably have a lot of paths displaying in the MRU (Most Recently Used) list, which appears in the Folder dropdown menu. If so, you may at some point in time want to clear that list or even edit it — especially if it contains paths that you no longer use. Here’s how:

1. Launch the Registry Editor (Start->Run->Type "Regedit.exe").
2. Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU.
3. One-by-one, delete each string value you don't like by selecting it and pressing the Delete key.
   
4. To Clear the list completely, Select them all and press the delete key.
5. To Edit Individual strings, double click the one you want and change the Value Data and click Ok.
6. Close Regedit. Takes immediate effect.
