Adding new time servers using the Registry

Using Control Panel, you can change the Internet Time settings to anything, but the list only allows you to store one extra entry. If you want to add multiple addresses to the list, you’ll need to use the Registry.

Warning:¬†This is a friendly reminder that editing the Registry is risky, and it can cause irreversible damage to your installation if you don’t do it correctly. It’s recommended to make a¬†full backup of your PC¬†before proceeding.

  • Use the¬†Windows key + R¬†keyboard shortcut to open the¬†Run¬†command.
  • Type¬†regedit, and click¬†OK¬†to open the Registry.
  • Browse the following path:¬†HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers
  • On the right side, right-click on the¬†Servers¬†(folder) key, select¬†New, and click on¬†String Value.


  • Type a number that corresponds to the position of the new entry in the server drop-down menu in Control Panel.
  • Double-click the newly created¬†String Value.
  • Type the address of Network Time Protocol (NTP) server. For example, if you want to use the Google Public NTP server, you can enter¬†



  • Click¬†OK.

Once you completed the steps, you can use the instructions to change the time server, but on¬†step No. 6¬†select the newly added server and don’t forget to click the¬†Update now¬†button.
