36.Banning Programs from “Most Frequently Used” list

Take a look at this for it is very interesting. If any of the following words or phrases is included in the program's shortcut name, the program will be excluded from the list: Documentation, Help, Install, More Info, Readme, Read me, Read First, Setup, Support, and What's New. Additionally, the following executables are excluded from the list: Setup.exe,Install.exe, Isuninst.exe, Unwise.exe, Unwise32.exe, St5unst.exe, Rundll32.exe,Explorer.exe, Icwconn1.exe, Inoculan.exe, Mobsync.exe, Navwnt.exe, Realmon.exe, and Sndvol32.exe.

Run the Registry Editor and go to HKEY_CLASSES_ROOT\Applications. Underneath this
key, you'll find a series of subkeys, each representing an application. The primary purpose of these su-keys is to determine whether the program appears on the Open With dialog box that appears whenever you try to open an unknown file type. But you can also add a value to any of the subkeys which will ban programs from appearing on the Most Frequently Used Programs List.

Look for a subkey that is the executable name of the application you want to ban from the list; for example, visio.exe for the Visio business illustration program. Once you find the application's subkey, create a new String value for that subkey, named NoStartPage. Leave the value blank. Exit the Registry. You might have to reboot for the setting to take effect and the program to be banned from the list.
