ZSoft Uninstaller
ZSoft Uninstaller is the better and easier way to uninstall programs on your computer.
ZSoft Uninstaller can be used as a Add/Remove applet replacement, but not only that, it can also:
- Analyze an installation so it can be completely uninstalled (also supports reboots of the computer as the process is split into two: Before and after the installation)
- Find and delete temporary files
- Delete entries from programs that are no longer installed
- Hide Windows Updates
- Hide entries from the list that you are never going to uninstall (drivers etc.) making the list smaller and therefore easier to manage.
- Show more information than available though add/remove
- Automatically find entries from programs that are most likely already uninstalled
- Automatically find entries that are considered "crap-ware"
- (Off course) search the list of installed software
