Doing this manually via Control Panel is tedious, but WMIC can automatically uninstall many applications with a single command. To see how, enter: wmic product get name. -- and look for the name of the program you'd like to remove.Then enter the name as it appears in that list, in a second command, like this: wmic product where name=windows live writer call uninstall. -- and your specified program will be uninstalled automatically, without you even seeing the uninstall program.MIC can, say, also close all the instances of a particular program. So if you want to shut down all Internet Explorer windows, for instance, then the command: wmic process where name=iexplore.exe call terminate. -- would do the trick, closing every instance immediately.
