I suspect it's because of some update W dl without me knowing, but just yesterday when I pluged my phone via USB or tablet or any external device for that matter, it did pop up in Windows Explorer and I could transfer data to and from it. Today when I plug in any of those devices(phone, tablet, flash drive) they don't. I can't even see them in Disk Managment. What could be an issue here? Is it indeed some broken update?
