2. Type regedit, and click OK to open the Registry.
3. Browse the following path:HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows DefenderQuick Tip: You can now copy and paste the path in the new Registry’s address bar to quickly jump to the key destination.
4. If you don’t see the DisableAntiSpyware DWORD, right-click the Windows Defender (folder) key, select New, and click on DWORD (32-bit) Value.
5. Name the key DisableAntiSpyware and press Enter.

Double-click the newly created DWORD and set the value from 0 to 1.
