by Media filter library i mean the standard filter thats there and lets you se .avi files and so on (the one that comes with windows)
i installed some nasty code into it and now its ruined T.T and i need to reset it
Reinstall not a option.
system restore forget it.
its not a 3rd party software causing the problem its code injected into the windows filter
(it belonged to a onld game or sumting and i installed it and it fucked up
probably cos its so old so its not a virus/spy ware just a error T.T)
