OK well something is very strange here, I tried step 1 a repair, no difference, I tried step 2 a rest which it warned I was going to lose all my history, favourites and site settings etc. This DID NOT happen and after I rebooted the PC I was still logged into YouTube.com and when finally I went to do step 3, it has the "uninstall" button faded out and I cannot use it?? How is this possible? I even closed Edge just in case it running was an issue, I still couldn't uninstall it.
