Default Behavior

S3cap is a kernel device driver. In Windows 7 it won't be started if the user doesn't start it. If S3cap fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the s3cap service is not running because of the error.

Restore Default Startup Configuration for S3cap

1. Select your Windows 7 edition and service pack, and then click Download.

2. Save the Win7_s3cap_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The s3cap service is using the vms3cap.sys file that is located in the %WinDir%\system32\DRIVERS folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
