On Windows 7, is the way to sync the clock to the time server more frequently still the same as before (by regedit)?

Are there other ways such as by using the control panel or system tool?

It's the same. It hasn't changed since Windows XP.

To change the delay, simply edit the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\w32time\TimeProviders\NtpClient

The value there is the number of seconds between updates.

I found that it was W32time ("W" instead of "w")... shouldn't matter since it seems case insensitive. –  動靜能量 Nov 28 '09 at 18:27
    
Windows is case-insensitive. –  Andrew Moore Nov 28 '09 at 19:39

Atomic Clock works well for me. But it is not yet officially supported on Windows 7 from what the notes say. But it works for Windows Vista, so it could still work.

In Windows 7, the registry key is modified to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\w32time\Config\UpdateInterval
