    • HKEY_LOCAL_MACHINESOFTWAREpoliciesMicrosoftWindows Defender
  • Start the ‘DisableAntiSpyware’ file, set the value data to 1 and press enter.

If there is no DWORD file in your case, right-click on the “Windows Defender” folder in the left navigation pane, select “New”, then click on “DWORD Value (32-bit) “. From there, rename the new entry to “DisableAntiSpyware”. Now open the newly created entry to set its value to 1 as shown above. This will disable your Windows Defender.
