This "Updating HP Prime" screen you describe. Does it say "Recovery mode" at the top?

We've gotten some indications that the latest Windows 10 update on some systems causes the calculator in the older "Recovery mode" update method to sometimes take 6-7 minutes for windows to detect the USB device. After that, it proceeds normally.

The newer update method that sends some files across separately, and then reboots to update should not have that method. Could you describe more precisely how you trigger your update? What version you have currently on your device?
