Changing
The Internet Time Update Synchronisation
To change the interval that Windows updates the time
using the internet time servers via regedit, navigate
to:
1. HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services
\W32Time\TimeProviders\NtpClient
2. Select "SpecialPollInterval"
3. Change decimal value from 604800 to a different value
in seconds. i.e.: 172800 (2 Days) or 86400 (1 Day) and
so on.
We don't recommend changing this unless you are on a
broadband connection.
