windows media player - get rid of it

[pipleighter]

I run W-XP and had WM 9 installed - lovely. I then installed 10 and was Ok. I then tried to install 11 and it refused to validate (I am legal by the way)! I now cannot get rid of it to re-install 9. I have tried:
uninstall from control panel
deleting every entry I could find in registry
uninstalled using the uninstall key from registry
deleting every possible mention of it in explorer

All I get is that there is a newer version running on my computer and set-up will now close.

Please can someone tell me how to "permanently" get rid of it.

Thanks

PS: I did post this before but it seem to have disappeared??

No guarantee but I suggest you download CCleaner and run it's Windows scan and Applications scan, and be sure the run the Issues scan.  When running the latter, CCleaner will ask you if you want to backup your Registry.  Say yes and then proceed with the scan.  Fix all issues it finds.
