Default Behavior

The Arc service is a kernel device driver. In Windows 8 it will not be started until the user starts it. If Arc fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the arc service hasn't been started.

Restore Default Startup Configuration for Arc

1. Select your Windows 8 edition, and then click Download.

2. Save the Win8_arc_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The arc service is using the arc.sys file that is located in the %WinDir%\System32\drivers folder. If the file is corrupted or deleted, you can put it back in there.
