I was getting an error code 80244FFF since November 20th, prior to that, I had no problem getting windows updates. I tried your solution as per above, it noted no corruption found but proceeded with the restore health command. I ran windows update again, I still receive the error 80244FFF.
I also tried troubleshooter, it detected problems but said it fixed them. I ran update again, and I still get the same error 80244FFF.
