Hi
The Internet update time can be altered via the Registry:
Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient
and double click on 'SpecialPollInterval' in the right hand pane - default is 604800 (7 days) in seconds (Decimal). You can change the Decimal value to what ever you want. I have mine set to 86400 (24 Hours). You will need to restart your system for this change to take effect.
**If you do alter this key, please backup the Registry first -
