Windows Embedded – disable/enable W32Time “Windows Time” service

Posted by jpluimers on 2010/03/15

In some environments having the “” service (W32Time) running is not desirable.

Circumstances where you might want to disable W32Time include:

  • scheduling algorithms that are sensitive to sudden time changes
  • usage of other time synchronization mechanisms

Not all Windows Embedded systems include the desired components to disable or enable the W32Time service from a UI (especially when they are not using the Windows Explorer as a shell), so here are two batch files that can help.

Batch file to stop and disable W32Time:

net stop W32Time
sc config W32Time start= disabled

Batch file to enable (auto) and start W32time:

sc config W32Time start= auto
net start W32Time

    OMGWTFBBQ do they still have that stupid time syncing in Windows 7??!?!?? I’d recommend using a real NTP client that just keeps your clock within margins so that there are no ‘sudden jumps in time’…
