    Does this update prevent companies like Nvidia and Google from streaming from our devices to their printers? I see that it claims to improve security and fix an issue with printers. But it does not mention removing Nvidia’s registry entries many of which are owned by “remote computer” or “interactive user.” I have been removing these entries for over a week, I have Nvidia .dlls and I have print, printer and printing.dlls all set up to streams to printers. And I do not even have a printer.

    I have Nvidia files that are scripted to print to google. I have Nvidia files that show a lot of fishy things such as bypass windows firewall and override this and that. I also have windows files from systemresources that shows there appears to be a hidden user on my desktop, that is somehow using tablet mode. On a desktop with an LED TV as a monitor, on a desktop that is not touch screen nor has it ever been attempted to enter tablet mode. On a desktop with only one account, windowscortanapersona.pri shows the activity of this “user” but i can’t find them anywhere in my pc.
