Default Behavior

TDPIPE is a kernel device driver. In Windows 7 it won't be started if the user doesn't start it. If TDPIPE 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 TDPIPE service is not running because of the error.

Restore Default Startup Configuration for TDPIPE

1. Run the Command Prompt as an administrator.

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

sc config TDPIPE start= demand

3. Close the command window and restart the computer.

The TDPIPE service is using the tdpipe.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.
