Increase automatic System Restore points to more than just once a week?

Question

I've been using Windows XP for a while now, but just recently upgraded to Windows 7. I'm used to Windows XP automatically creating a new System Restore point once a day.

I notice that Windows 7 automatically creates one only once a week. Why is that? And how can I increase the frequency?

Solution

In the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore, set the RPGlobalInterval value, the number of seconds between restore points, to a smaller number, such as 86400 (decimal) for once every day.

For more information, see this blog post, as well as this Microsoft Community Forums thread.

Note: If this doesn't work, try @Thraka's answer, which involves modifying the System Restore scheduled task.
