Hi!
I'm writing a program, and some parts of it can work correctly only if the Internet Time is enabled in the Win10 settings.
How can I check through C++ code if it's turned On?
The program runs in other people's PCs, so the goal is to be able to do this without any additional settings, or system variables (for example in the Registry Editor).
This is the setting's place in the Control Panel:

Is your goal to actually check that settings is on, or that the time is correct (for some reason)?
The final goal is to make sure, that the User has a correct time, and the settings are not manipulated.
For a standalone system changing the system time and these Control Panel settings (and the registry key mentioned below by @Castorix31 requires Administrator privileges. So, for a standard user it seems to me that this is a non-issue.
The program is planned to be sold to individuals too, and they have to ability to use their Admin privilige in their own PC or laptop.

So it will be a futile exercise to attempt to restrict access to date/time settings. After all, the Administrator could simply uninstall your program!
The problem was solved by @Castorix31 's suggestion. I needed to make sure that if the User is on a trial version, he can't set the computer's time back to work around the trial's datetime limit.
It is stored in the registry, at :
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W32Time\Parameters\Type
(NTP if configured)
