Windows 10: WINDOWS 10 Automatic Time Sync Interval Minimum

I want to use Windows 10 with automatic time synchronization, but each computer has a different minimum value of sync interval.Some have a minimum of 1024 seconds and others have a minimum of 15 seconds. What's the difference?**Moved from Windows / Windows 10 / setting

Windows 10: How to change a theme slideshow time interval?

If you want to set intervals of your choice, you can do it by modifying the registry. Please follow the below steps to set the slideshow intervals:

1. Open Run and type regedit.exe
   
2. Navigate to:
   HKEY_CURRENT_USER\Control Panel\Personalization\Desktop Slideshow
   

In here, the two important values are the Interval, and Shuffle.

Double click on Shuffle, and change the value to 1. OK.

Then change the Interval by double clicking on it. You'll first want to change the Base to Decimal, rather than Hexadecimal (otherwise you'll get unexpected interval values). Then change the value to your desired time, in milliseconds (10000ms for 10 seconds).

You can exit regedit now. The final step is to restart Explorer. You can do this through Task Manager if you know how, otherwise simply restart your computer.

 

Unable to sync Windows 10 time with time servers

I have a new, OEM installation of Windows 10 that is unable to contact any time servers to sync the system time. Each attempt gives me a timeout error, and pinging the time server times out as well. Here is what I've tried:

• Checked that the Windows Time service is running and set to automatic startup, and restarted it
  
• Disabled my firewall
  
• Tried using time.nist.gov, which is currently working according to NIST
  
• These steps using w32time, which appeared to succeed but didn't update the time
  

The time is currently off by 7 hours, which shouldn't be far enough to break Internet syncing.

EDIT: Just tried the same steps on my other computer which boots only Windows (albeit an longer-standing installation of 10), and had the exact same issue, except when I try syncing it simply says "An error occurred when Windows was synchronizing with time.nist.gov." So I highly doubt it is dual boot-related. What is going on?
