122. Restrict Certain Users From Running An Application

You can selectively restrict access to few apps and file names. To do this, open registry and
navigate to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now look for a subkey by the name DisallowRun. Within this key, add many string keys you
like each mapped to an application or file that you want to be restricted.
