Clear Recent Commands From the Run Dialog in Windows.

Clear Recent Run Dialog Entries Through Regedit

Open up regedit.exe through the start menu run box, and then navigate down to the following key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU

You'll see all your recent commands on the right, and you can delete any of the keys that contain your commands. You'll have to logoff and then back on, but the list should be clean.

Note that this will also work for Windows Vista's Run dialog

The Easier Way is,

• Right-click on the taskbar and choose Properties, then choose Start Menu.
  
  
• Select the "Classic Start menu" option, and choose the Customize button.
  
  
• Now just click the Clear button to remove all of the recent documents and applications from the start menu.
  
  
• Once you've done that, hit Cancel and then Cancel again to make sure you don't switch to the Classic Start menu.
  
  
• Note that this method will clear out everything… so if you just want to remove a single entry you need to use the registry hack method.
