Managing "Run as " Option
by Webmaster on May.18, 2010, under Windows 7, Windows Vista, Windows XP
The RunAs Command option is great but sometimes its best not to allow users to have access to that feature. Disabling it is quick and simple, all we need to do is edit the registry.
First load up regedit (Start -> Run then type regedit and press the Ok button) and follow this path HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows -> CurrentVersion -> policies -> Explorer. From there create a new DWORD value and name it HideRunAsVerb and give it a value of one. Once that’s done you’ll need to restart your machine. Now users won’t have the ability to run programs as other users.
