Run command history

Most of you're in search of about how to delete the run command entries,the run command keeps list last commands or any filename used i.e commands,filenames,features etc . The used commands filenames etc are in most recently used list(MRU).Run commands are used as a shortcut option, because instead of going to the actual location and opening that file might be too boring for people like me, so we used shortcut run commands.Like when your enter the run command, it points to the location which you've entered.however some option i don't want other people to make use of those run commands, so it's better to delete that command
Most of the utility such as calculator,notepad, registry entries are opened using shortcut run commands
