I am currently running windows 10 on my system and waited over 2 hours for the update to download only to get this error at the end of the download session:
Unable to update .. please contact Microsoft Support with an error code of 0xC1900200.* Update- I used the MS tool specifically for this and I am now on the new windows 10..
I do not know what to do since I had repaired with a MS tool the update assistant. I don't know what that means or how I can get the upgrade.
