Try this it worked for me.
- Make sure your Windows is up to date.
- Install if you do not have it Xbox app.
- Important under the Xbox app select My apps.
- It should show the update.
- If it does not show re-boot your computer and try again.
I know this is more then ridiculous for any update. We are stuck with this nonsense.
There is no sense to go on because it just gets me upset.
Good Luck
