Problems: My Windows 10 ussually has wrong time after I have fixed it after 3 - 5 days. The time server had been set with update automatically option was checked but it not works. So what is my problem?
Windows has a service named Windows Time (check in services.msc) which handles the time updating work. For some unknown reason, this service be set as Manual, so it can't work correctly
==> Run services.msc ==> Double click on Windows Time --> Change Startup Type is Automatically (Delay start) & check the result :)
