Custom Vista Restore point time interval saves hard disk space

If you enable system restoration in Windows Vista, the system automatically creates a system restore point based on a certain period of time (the default interval is one day. Over time, the System Restore Point will become larger and larger, occupying larger hard disk space.

In this regard, we can consider modifying the time interval for the system to create a restore point. For example, we set it to let the system create a restore point every two days. In this way, you can avoid worries (such as system faults) and avoid disk space occupation. The method is as follows:

Run the registry and expand it to the following branch: HKEY_LOCAL_MACHINE/software/Microsoft
/Windows NT/CurrentVersion/systemrestore.

In the right-side window, find and double-click "rpglobalinterval". In the displayed window, the system displays the value "15180" (in seconds, 1) in hexadecimal notation by default ).

For ease of conversion, please click "decimal" in the middle. The window above will change to the interface shown in Figure 2:

In Figure 2, "86400" seconds is the time of one day. If you want to set the system to create a restore point in two days, it is "86400 × 2" (172800 seconds ), if you want to create a restore point in three days, it will be "86400 × 3" (259200 seconds), and so on.

After modification, restart the system to take effect.
