     • Double-click on the newly created “DisableAntiSpyware” DWORD to edit its Value Data.
     • Set the Value Data to “1” (without quotes).
5. Safety Tip: Create a System Restore Point:
   • Before making any changes to the Windows Registry, it’s a good practice to create a system restore point as a backup in case anything goes wrong. To create a system restore point, you can:
     • Type “Create a restore point” in the Windows search bar and open the corresponding settings.
     • Click the “Create” button in the System Properties window to create a restore point.
