Whenever WIndows Update messes with your SmartSDR CAT, it is not necessary to uninstall and re-install SmartSDR. In fact, that may not really solve the problem if SmartSDR CAT isn't selected to be uninstalled/re-installed when redoing SmartSDR as Mark mentioned. The simple repair and reboot of your PC should resolve problems after Windows Update without resorting to Jim's "nuclear option!"
Just be careful of the flex uninstall anti logic with reference to Dax & Cat
The uninstall program asks if you want to leave Cat and Dax installed. Normal logic is asking if you want to uninstall them so if you don't read the message and click "Yes" thinking you are uninstalling them, they remain on your system. The correct answer is "No" :)
This is against normal windows convention when uninstalling programs.
Simple answer long term (once I found out what caused the problem) :-
disable DAX and CAT from being allowed to auto start, then create a bat file/script that terminates and unloads both from ram before doing an shut down (3 lines of code required). Never failed me yet and I have taken every update of W10 even the pre-release stuff.
