  1. Windows defender folder is missing in gpedit.msc & regedit. I cant turn on my windows defender, it says “this app is turn off and isn’t monitoring your computer”. What should I do?

    • Go to “services.msc” page and look if is there “Windows defender” service missing or not? If it is missing then download and run “windefend.reg” file.
