Change Vista automatically create system restore point interval

System Restore for the normal operation of Windows system I believe friends are very clear, simply put, when the Windows system fails, we can use the previously created normal operation System restore points to restore the system without having to reinstall to avoid the loss of important data and programs. After enabling System Restore in Windows Vista, in addition to manually creating system restore points, the system can also automatically create restore points, especially when the system monitors changes, such as installing new hardware, patches and applications, in addition, Windows Vista It also automatically creates system restore points for a certain period of time—the default interval is one day—to ensure that we can restore the system to its most recent security state.

However, sometimes we may need to change the time interval in which Windows Vista automatically creates system restore points. For example, in order to save disk space, you may want to increase the time interval for Windows Vista to automatically create system restore points. If you want to automatically create a system restore point at a higher frequency when you change your system frequently, can Windows Vista support such "flexible" customization?

The answer is obvious. This can be done by modifying the registry. The following describes the specific steps:

1. Enter "regedit" in the search box of the Windows Vista start menu and press Enter;
2. Registry editing will trigger UAC and pop up a prompt window, click Confirm to continue;
3. Locate the following registry branch:
   

   HKEY_LOCAL_MACHINE
   – SOFTWARE
   – – Microsoft
   – – – Windows NT
   – – – – CurrentVersion
   – – – – – SystemRestore
   

4. In the right panel, find the registry key named “RPGlobalInterval”;
5. Double-click the registry key to see that the value defaults to 86400 (decimal) or 15180 (hexadecimal) - Note: The unit is seconds, which is one day - to modify it to the desired value.
6. Reboot the system after the modification is complete.
   
   

   Note: This method is also applicable to Windows XP.
