`HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer`

  • Look for a DWORD entry named **SmartScreenEnabled**. If it does not exist, create it by:
  • Right-clicking the right pane, selecting **New > DWORD (32-bit) Value**.
  • Naming it SmartScreenEnabled.
  • Set the value of SmartScreenEnabled to one of the following based on desired behavior:
  • `Off` to disable SmartScreen.
  • `Warn` to receive warnings but allow execution.
  • `RequireAdmin` to require administrator approval for unrecognized apps.
  • Close the Registry Editor and restart the computer.

Below is a reference table summarizing SmartScreenEnabled DWORD values:
