Are you saying you have just received version 1809 of Windows 10 that was released in October 2018.
My computer just got the 1809 update about 2 or 3 weeks ago... (even though I use it daily and windows does its updates regularly)....
It totally borked my account, all my documents were missing, my desktop was wiped, it was totally jacked... Thankfully I was able to rollback to the previous version and everything was okay. I've paused updating until I get a chance to do a full backup this
weekend then I'll give it another shot.
This 1809 update is faaaaaaaaaaaaar from seamless... I've read so many horror stories from the past few months. IMO Microsoft should have not re-released it until they tested it more thoroughly and ensured it wasn't going to wipe people's systems like it
is still doing. Especially with forced updates now it is more critical than ever.
