You can selectively restrict access to few apps and file names. To do this, open registry by going to
START-RUN and entering regedit. Navigate to
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion \Policies\Explorer] and a
sub-key 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.
