Turn off Windows Defender permanently via Registry


Anti-malware and the anti-virus protection suite Windows Defender now comes pre-installed with the latest, Windows 10. It’s fairly decent in keeping your computer safe from various security threats, though it doesn’t hold up to other free and paid alternatives out there. Windows Defender is also smart enough to disable itself when you install a compatible third-party anti-virus, but Microsoft doesn’t make it easy to turn it off permanently on your own. Disabling Windows Defender can open your computer to threats.

While holding down the Windows key, press the R key. Alternatively, go to the start menu and search for Run and open it. Type in Regedit and click OK. If User Account Control asks for permission, click Yes. Head to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender. You can also copy and paste that address into the Registry’s address bar. On the right-hand side, right-click in the empty area, choose New > DWORD (32-bit) Value. Type in DisableAntiSpyware and press the Enter key. Double-click the DisableAntiSpyware key. Type 1 in Value data and hit OK. Restart your computer.
