To disable a program by policy you need to set the use of the 'blacklist' globally first and then your list of disallowed apps is used:

REGEDIT4

;Enable blacklist of applications that should not run
[HKEY_LOCAL_MACHINE\Security\Policies\Shell]
"DisallowRun"=dword:1

;Add entries to blacklist of applications that should not run
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun]
"1"="fexplore.exe"
"2"="iexplore.exe"
"3"="clock.exe"
