Windows 7 Intelligent Create restore point saves hard disk space

In the Windows XP era, users can resolve backup restores in a ghost manner. But when the operating system into the Windows 7 era, the use of Ghost way backup restore, obviously not as good as the system's own restore function. The problem is that after you enable System Restore in Windows 7, it automatically creates a restore point (the default cycle is one day). The more restore points you have, the less hard disk space will be.

As a result, we can consider having Windows 7 automatically create restore points that are more "intelligent", such as creating the system by default every day, and modifying it once every two days or three days.

　　Little knowledge: Windows 7 restore points that are not the same

There may be other users who do not know that Windows 7 does not automatically create restore points by default, and you must manually open related services (want to know how to manually turn on?)

Run the registry, and expand to the following branch: Hkey_local_machinesoftwaremicrosoft

Windows Ntcurrentversionsystemrestore.

Then in the right window to find and double-click "Rpsessioninterval", in the pop-up window you can see that the system defaults to "0" (unit seconds, Decimal, as shown in Figure 1).

Figure 1 Default value for Rpsessioninterval

For convenience conversions, select "Decimal" in Figure 1, then the value "172800" (do not enter double quotes), as shown in Figure 2:

Figure 2

In Figure 2, "172800" represents 172,800 seconds, which is two days. If you want Windows 7 to create a restore point every three days, enter "259200" in decimal. Analogy
