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. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config s3cap start= demand

3. Close the command window and 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.
