Rolling Back Windows Media Player 10

So I go through all the steps and roll it back, ya? It says it's been rolled back and everything, but as soon as I start up what should be WMP 9, 10 comes up again like nothing ever happened. If I try to install WMP 9 manually, it tells me 10 is already installed so GTFO. Any ideas?

uninstall WMP completely (control panel> add/remove programs>add/remove windows components)
install v. 9 from scratch
