In my time deploying enterprise ready windows builds around the world I have seen some pretty consistent configurations, which take us down a deep deep HOLE! of Group Policy.
Group policy is a familiar tool to everyone in the windows management / admin space. For years we have bet our device security and reliability on Group Policy and all too often taken advantage of all that we can do with it.. Often times finding ourselves in situations where we ask why did this happen, and the common response is "I don’t know! It was there when I picked up this mess" Well I often get asked at what point do I look over existing group policy to model our Enterprise ready build. My answer is Never! Well almost never, we might grab things like drive mappings, and 3rd party applications Reg keys in Group policy preferences, but aside from that STAY AWAY!
