I updated my Dell Laptop with Windows Media Player 9.0, by the way I have Windows XP, and now it runs reeeeeeaaaallllllyyy slow. I need to know how to uninstall it and and reinstall the version my laptop came with (8.0 i think). I scanned for viruses and adware and also cleaned out temporary internet files and cookies. I also have plenty of memory space so the problem is not lack of memory. If anyone out there can guide me on my quest to a speedy computer again I would be grateful.
