How to uninstall Unknown File Handler

Unknown File Handler is our small helper application that kicks in when you try to open a file you do not have a viewer or player for. It helps you find programs that we know will open the type of file you are having trouble opening.

If you wish to uninstall Unknown File Handler entirely, you will no longer be able to get (validated) suggestions for software to open files your PC cannot open.

You uninstall Unknown File Handler through the Windows Control Panel like any other software.

Uninstall entry missing

If you cannot find the uninstall entry, then something has removed it. Do you run any "system cleaner" or "system optimizer" tools that could have removed them? In that case try to re-download and install Unknown File Handler again. This will repair the uninstall option which you can run immediately after. Restart your PC before re-installing, and don't start anything before running the uninstaller. Download Unknown File Handler here.

Cannot open Add/Remove Programs

If you cannot open your Add/Remove Programs in the Control Panel, then something is wrong on your PC. Likely you associated shortcuts or executable files with another program, so Windows don't try to run them, but try to open them using another program. In that case, you need to restore the settings for your .lnk files. See this article from Microsoft: http://support.microsoft.com/kb/172053.
