MKRZero not working with most updated win10?

Hello all! I'm new to Arduino and hope you guys can help me.
I bought MKRZero a few days ago and I can use it without problem with a win10 laptop which is not fully updated.

Today I updated my win10 and suddenly the Ports cannot be found anymore in the IDE.

The LED on the board is on (so that means the USB port should be working, right?), but it seems the computer cannot recognize my board anymore or any of the ports...

Any ideas? Thanks!!

plz ignore this...hardware itself problem
