Looking at all the articles about this issue, this seems to be more about a bug in the Windows cleanup tool that lets the user delete old update files. Maybe the tool isn't working properly, or it's flagging update files as deletable and they're not supposed to be. Admin users can still delete whatever they want manually, unless the system or something else is currently accessing the file. The OS sometimes protects its system files by having them be owned by the SYSTEM user, but the admin can take ownership of them to delete them. This hasn't changed and I can't see it changing.
