Restrict loading of “Disk Defragmenter” snap-in into MMC.

MMC can load various snap-ins that are used to simplify system management tasks of daily routine. This setting can disable loading of the snap-in “Disk Defragmenter” into MMC.

Tweak for : Windows XP, Windows 2003, Windows 2000, Windows Vista
Microsoft Management Console tries to simplify system management tasks of daily routine. It has applications, which have been built with modules. These applications, called snap-ins, can be added to a program that works independently or as a part of the bigger application. Say, if you run “dfrg.msc” from Start > Run menu, you are loading the snap-in from the basic framework (MMC). MMC provides system administrators an adaptable interface to view the system and set it up.

The “Disk Defragmenter” defragments your drives so that your computer runs faster and more efficiently. This setting can restrict loading of this snap-in into the MMC.

For this, go to Start > Run menu, enter “regedit” and navigate to the registry path listed below. If any of the subkeys “\MMC\{43668E21-2636-11D1-A1CE-0080C88593A5}” does not exist, create them as explained below. Then, create a string value “Restrict_Run” in the right panel.

Now, right-click and modify its value to “1” which can disable snap-in. However, if you want to enable back the snap-in, delete the subkey “{43668E21-2636-11D1-A1CE-0080C88593A5}”.

The changes take effect after a restart or logoff.

NOTE:
Access to “Disk Defragmenter” from Start > Programs > Accessories > System Tools is also blocked.
