Some of you may have heard me talking about this one on the weekend, as this KB was released to the wild last Tuesday. Today I wrote a PowerShell script to test our domain at work to see what GPOs will have this problem after our scheduled patch maintenance this weekend, and see even we will have 42 GPOs with issues if I don't do the recommended fix. I even was on the phone from Microsoft before they admitted this is what happened and I recommend everyone whom looks after directories using GPOs evaluate this in their environment before this becomes an issue for them.
If anyone her wants my PowerShell let me know.
