I have a custom PCI board that I had been using the VISA driver wizard and LabVIEW with. It has been working fine until recently. I am able to write to and read from the board with no problems but the interrupts no longer work. The one thing that changed recently is MS forced an upgrade on this PC so I could have the latest X-Box and Candy Crush games. I am curious if anyone is aware if the Creators Update added some new layer of protection that breaks the interrupts.
