I am using the latest version of Windows as I just upgraded over the week end.i can't use my anti virus and some other vital programs.
If you're facing this kind of issue then you seems to be on insider preview of windows 10 which is not stable in this situation I recommend you to reinstall the RTM latest version available.
Sorry to say but I don't think their is any other solution available to deal with it
In this situation you must reinstall the windows 10 by keeping apps and file
