Tonight, completely randomly (not after a Windows update or anything) I get a notification that Windows is not genuine. I'm using SLP BIOS for my MSI P67A GD-55 B3 and it's been working fine for months. I tried updating the key and activation via command line with no luck. Then I tried updating the key via the control panel and it's giving me the error The Software Licensing Service reported that the computer BIOS is missing the required license. Is anyone else who was using modded BIOS getting this as of tonight? Did MS invalidate the OEM SLP keys?
