The download on mine got hung up at 1%!
Now I'll have to wait until my data 'bonus' time to continue the download. (2A-8A)
Doh, that's a nuisance Ken. Hopefully yours will install properly first time.
Thing is, a couple of days ago these updates were sitting there waiting for me to restart so they would install, which I did. Then today, I noticed the same update that had installed previously was downloading again, KB4494441 Checking the Windows build, it had the wrong build number, now after letting it install again it has the correct build number.
Stick this in google KB4494441 and you'll see others have had the same problem.
