OK, we'll try something else.
- Hit Windows key + R to launch the Run command, type: services.msc and click OK.
- In the Services console which opens, scroll down to Windows Time and double click it.
- Then change Startup type to Automatic.
- Click Apply/OK and then close the menus.
- Then repeat the steps to see if the error occurs again when you try to synchronize.
There are two options in the Startup type called Automatic and Automatic (delayed start), but you only want the first one.
