RIP Hope you get your files back The same thing (almost) happened to me today (05-14-2020). Around 10 AM, I was in the middle of doing a project on my laptop. I had a popup notification that my computer was going to restart to install an update (cumulative update for windows 10 KB4556799). I clicked the 'Not Now' box and continued working. These were supposed to only install after I approved and then, after 8 pm. After around 10 minutes the computer started the update without further notice. It seemed to take forever. Very unusual... Over an hour later it was finally finished. I resumed my work or tried to! Everything was gone except for very few things. :( The backup was turned off! No file history turned off too!! No restore point because 'a recent update had been performed within the last 10 days'! Most of the day I have been reading and searching for a way to recover all my disappearing files and work. No luck! I am shocked, confused, angry, and bewildered as to what happened & how to find everything.

Yes there ARE issues!! Patches to .net stops the digital pen cursor after lifting the pen from the pad and then touching the pad again. TechSmith's Camtasia and other screen recording software has been affected

I noticed strange behaviour of my dropdown menus especially in browsers Google, Firefox and Edge. Clicking the black arrow next to the dropdown field shows the options in less than a split-second. Not long enough to click a choice. Also the START Menu has a problem. When scrolling down to the item of my choice the moment I want to click it automatically scrolls back to START position. In Excel drop down menus work but cannot scroll the worksheet in horizontal way. Also this comes back automatically in start position. Can this be caused by the Update that took place yesterday evening on my computer?

After this last update I am unable to cast to (use as a remote wireless display) my Sony Bravia TV's, I was previously able to connect seamlessly. The computer sees the TV and the progress shows on the TV then it comes back that it is unable to connect. I don't know what to try. I have rebooted the PC and turned the TV off and back on and tried a different Bravia TV with the same result. Any suggestions?
