Applocker MMC Crashes in 2012 r2

When changing users and groups in applocker policies the mmc crashes. After a lot of investigation a lot of people said that it was a bug and it was fixed in Windows 10.

I identified the following .NET updates;

KB 4073700
KB 4055001
KB 4054980

I uninstalled all the above .NET and I could then edit the applocker rules.

On the 2nd dc i tried to figure out which one of the above updates caused the mmc to crash. I was lucky i started to uninstall KB4024847 and rebooted the machine and everything was working.
