I first posted this when Windows XP was still in beta. It applies to Windows
Vista as well.
Windows XP (and now Windows Vista), as loaded, automatically updates the
system time every 7 days from one of the (default) time servers. This
update interval can be changed as follows:
Go to Start/Run. Type in regedit (the registry editor), then press enter.
Using regedit, press control/F (search). Type in "specialpollinterval"
without the quotes. Press enter.
When search has found the first entry, double click on the highlighted name.
Change the "base" to decimal. You will see that the decimal value is 604800,
the number of seconds in 7 days.
Edit this decimal value to any value you desire, remembering that there are
86400 seconds in one day, 3600 seconds in one hour. Click O.K.
Press F3 to find the next entry. Do this for each instance of the decimal
value "specialpollinterval".
Exit regedit.
Now reboot your system for the change to take effect.
Cheers!!!"
