Com3 was working but after windows update it is not

I have been working fine using COM3 and the other night Windows (10) did an update and now I get COM3 denied prompt. Should i unload everything and start reloading everything back in?

Is this a good question?

Couple of suggestions: (individual suggestions, not a series of instructions)

1. Make sure you don't have the interface open more than once (with one connected).

2. Make sure the machine is has been unplugged from main power AND the usb for several seconds before attempting another try

3. Go to your device manager and verify whether COM 3 is appearing and disappearing when you plug in/remove BoXZY's usb from the computer. If not, does a different numbered port appear? Use that number

4. Try updating the Arduino software to the latest version.
