Exact same thing...
I got the "Important updates are pending" message. This notice came up several times on my Acer notebook running Windows 10.
I finally selected "Pick a time" then selected a time about one hour ahead and then closed all of the open apps and web sites. Then sat back and allowed the computer to auto start the updates.
When I came back, the screen requested the language option (English selected) then it continued to update with pleasant prompts stating not to turn the computer off.
Checked several times during the update process and saw calming messages like, "Leave everything to us" and "Making sure your apps are good to go."
When finished, the entire hard drive is deleted. All files, docs, pictures and desktop icons are gone.
The dialog box that comes up says, “Location is not available"
C:\WINDOWS\system32|config\systemprofile\Desktop is unavailable.
This is completely outrageous. "Unavailable" is an understatement. I have a black screen!
The start button with the logo is at the bottom of the tool bar - but does nothing.
There is a search icon in the toolbar - does nothing.
There is a task view icon in the toolbar - does nothing.
There is no internet connection (either wireless or hardwired plugged into the router - tried both), no desktop, no apps, no browser, docs, picture, nothing but a recycle bin.
The notebook battery indcator icon in the toolbar seems to be functioning.
Yes, tried to restart many times - no change.
I’m not a computer expert – but I’ve been using Windows since it first came out. I have never seen anything like this.
For a forced update on an OS like Windows 10 – in this day and age – to completely trash a customer’s computer - this is unacceptable.
I am beyond angry.
