mst Defrag Home Edition


mst Defrag Home Edition is a software program developed by mst Software GmbH. The most common release is 3.6.0, with over 98% of all installations currently using this version. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background.

Delaying the start of this service is possible through the service manager. The setup package generally installs about 6 files and is usually about 2.92 MB (3,060,224 bytes). The installed file update.exe is the auto-update component of the program which is designed to check for software updates and notify and apply them when new versions are discovered. Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows XP. While about 41% of users of mst Defrag Home Edition come from Germany, it is also popular in the United States and United Kingdom.
