Right-click on the folders, go to Properties. Click on the Security tab. Click the Advanced button. Take ownership of the folder structure and push it down the tree. Set the ACL to permit full control to your user. Delete away. Be warned, however, it’ll likely show up again during the next patch cycle.
Yeah I know how to do that, but I really don’t want to mess with folder permissions since that tends to generate more problems later. I just wish microsoft would stop pushing multiple copies of the same software onto my computer. It acts more like a virus than a service.
