How to Uninstall Windows Live OneCare
"I tired out Windows Live OneCare and now I can't figure out how to get rid of it. What do I need to do to uninstall Windows OneCare from my computer?"
Ideally you should be able to remove Windows Live OneCare simply by going to Add or Remove Programs (aka Programs and Features in Windows Vista). If that doesn't work, Microsoft also offers a tool to help in uninstalling OneCare from your system.
Go to Start > Control Panel > Add or Remove Programs
Scroll through the list of installed programs on your computer until you find Windows Live OneCare in the list. Select the program in the list of installed programs and click the Uninstall button.
If this does not work, you can use the Windows Live OneCare Uninstaller OneCare Cleanup instead. Just download OneCare CleanUp directly from Microsoft via that link and remove OneCare from your computer.
