You can easily hide or show run command from Start menu of Windows. First of all you have to log in from user who have Administrative rights and then load Windows Registry Editor by typing “regedit” in Run Command without quots.
If you want to hide Run Command only for logged on user then open this path.
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
If you want to hide Run Command for every user of Windows then open this path.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer


After opening this path. Create a new key. NoRun (String Type) and enter value 1 in it.

After creating this key restart or log off your Windows to take effects. If you are using Microsoft Windows 98 then you have to restart your windows. After restarting or logging again your windows you can’t see Run Command in your Start menu.
If you want to show again Run Command in Start menu then remove key from Registry which you created above.
