This post is for Windows 8.1 users with Xfinity Online TV Error Messages.
I hope there only a few of you. Let's try everything else first before we consider doing a "REFRESH".
A refresh can be done two ways. One will set your computer back to FACTORY SETTINGS. This means you will lose all files, all added software, all added browsers and your computer will be returned to Windows 8
The other way you can keep your personal files and passwords. You will lose all added software and browsers, also returned to Windows 8
If you have purchased software online or have a recovery back up disk all of this can be reinstalled. You will need your user names and passwords for your software, most recovery disks even require license and password info.
I have been thru this process myself. Careful preparation can make the process easier. After doing this I was advised by Microsoft Support to reinstall Windows 8.1 before reinstalling my antivirus. This procedure made an incredible difference.
I just wanted you to consider this if we have tried everything else without a positive result.
Clearly the Windows 8.1 users with Error 422 problems may be the most difficult to repair.
