TCP/IP Registry Compatibility (tcpipreg) Service Defaults in Windows 10

Provides compatibility for legacy applications which interact with TCP/IP through the registry. If this service is stopped, certain applications may have impaired functionality.

Default Settings

Startup type:Automatic
Display name:TCP/IP Registry Compatibility
Service name:tcpipreg
Service type:kernel
Error control:normal
Path:%SystemRoot%\System32\drivers\tcpipreg.sys
Registry key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpipreg

Default Behavior

TCP/IP Registry Compatibility is a kernel device driver. In Windows 10 it is starting automatically when the operating system starts. If TCP/IP Registry Compatibility fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the tcpipreg service has failed to start due to the error.

Dependencies

TCP/IP Registry Compatibility cannot be started under any conditions, if the TCP/IP Protocol Driver service is disabled.

The tcpipreg service is using the tcpipreg.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 10 installation media.
