Default Behavior

Windows Time is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Windows Time service is started, it runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Windows Time 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 W32Time service hasn't been started.

Restore Default Startup Configuration for Windows Time

1. Run the Command Prompt as an administrator.

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

sc config W32Time start= demand

3. Close the command window and restart the computer.

The W32Time service is using the w32time.dll file that is located in the %WinDir%\system32 folder. If the file is corrupted or deleted, you can put it back in there.
