Default Behavior

Windows Time is a Win32 service. In Windows XP it is starting automatically along with the operating system. Then the Windows Time service is running as LocalSystem in a shared process of svchost.exe. Other services and drivers are allowed to run in the same process. If the Windows Time fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the W32Time service has failed to start.

1. Select your Windows XP edition and service pack, and then click Download.

2. Save the WinXP_W32Time_Service_Startup.cmd file to a local storage device.

3. Run the saved file.

The W32Time service is using the w32time.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows XP installation media.
