How to delete Run history in Windows?

Whenever I press Win + R , Run dialog box appears so that commands such as temp or %temp% can be typed in. I did this in order to delete temp files, etc.

When I again press Win + R, the old commands used are still listed in the box.

How do I prevent this history from recurring ?

You can prevent history from recurring this way :

1. Open Registry Editor by typing regedit in the Run dialog box
2. Find this :

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerRunMRU

3. In the right panel, you will find the entire history. Select all the strings except the Default string and delete them.
4. And Your’ done.
