Dave, I just read your message and all of the replies don't ask what kind of virtual serial ports you are using. If you are using com0com ports, the signed driver on the 64 bit version of the com0com drivers expired.
If this is the case, just a hunch here, go into the device manager and right click on the driver / item that has the yellow option where it's not working anymore. Select search online to update the driver and if this is the issue, you will get a new driver and then reboot. All will be back to normal after that. Hope my hunch was correct. Max NG7M I realize this is not a Windows list, but it relates to my K3 as I use it and the K3 Utility to do things... early this morning, Windows tried to install (but failed) 2019-07 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4507435). As a result, I have lost my virtual com ports... in Device Manager, under USB controllers, they show as USB Serial Converter (with a yellow triangle with an exclamation mark inside it), and have the correct driver loaded, but somehow they are not working, not findable in the K3 Utility, and so I am at a loss what to do /change / fix next... Any help will be greatly appreciated. Thanks & 73 de Dave, W5SV -- M.
