Default Behavior

Windows Connection Manager is a Win32 service. In Windows 8 it is starting automatically during the operating system startup. Then the Windows Connection Manager service runs as NT Authority\LocalService in a process of svchost.exe, sharing it with other services. If Windows Connection Manager 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 Wcmsvc service hasn't been started.

Dependencies

Windows Connection Manager can't start, if the Remote Procedure Call (RPC) service is disabled or not available.

All the services listed below will not start if Windows Connection Manager is disabled:

Restore Default Startup Configuration for Windows Connection Manager

Before you begin doing this, make sure that all the services on which Windows Connection Manager depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

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

sc config Wcmsvc start= auto
sc start Wcmsvc

3. Close the command window and restart the computer.

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