Ok, so I am definetley not crying wolf here. After installing Build 9860, I got an error message in the Action Center that says my virus protection, amd anti-spyware was off in Windows Defender. I went to go turn it back on but I cant. It says that it cant verify the digital signature, and due to to a recent software change (AKA Build 9860), blah blah. I just put a back up Anti-Virus Program on here really fast so I dont get infected, but can someone please give me a list of programs that are not sketchy and that work with this current build of Windows Tech Preview? Thanks. And also if you know how to fix Windows Defender, could you help me on that too? Thanks. I would really appreciate it.
