All of us use Start menu RUN dialog box to enter frequent commands in Windows. It stores the entered commands in its history and suggests them whenever we enter them next time.
Although its a good feature but sometimes we might want to remove a particular item from the history list because of some obvious reasons.
Here is a simple and safe method to remove any desired item from RUN history / MRU (Most Recently Used) list:
1. Type regedit in RUN dialog box and press Enter. It'll open Registry Editor.
2. Now go to following key:
In right-side pane, you'll see various String values with the name a, b, c, etc and their value will be set to the command which you entered in RUN dialog box:
3. You just need to delete the String value which contains the command which you want to remove from RUN history list. e.g. if you want to remove "msconfig" command from RUN history, then delete the "b" String value.
4. That's it. Now the deleted command will no longer appear in RUN MRU list.
