Windows 7 intelligently create restore points Save hard disk space

In the Windows
XP era, users can solve backup and restore through Ghost. But when the operating system
enters the Windows
7 era, using Ghost backup and 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 period is one day). The more restore points, the less hard disk space will be.

From this, we can consider letting Windows 7 automatically create restore points more "smart", such as the system defaults to create once a day, modified to create once every two or three days.

Tips: Not the same Windows 7 restore point

There may be some users do not know, Windows 7 does not automatically create restore points by default, you must manually open the relevant services before you can (Want to know how to open it manually?

Then find and double-click in the right window. ;RPSessionInterval”, in the pop-up window, you can see that the system default is “0” (in seconds, decimal, as shown in Figure 1.)

For easy conversion, please select “decimal” in Figure 1, then the value "172800" (do not enter double quotes), as shown in Figure 2:

In Figure 2, "172800" represents 172,800 seconds, which is two days. If you want Windows 7 to be created every three days One restore point, please enter in decimal (“25 9200” OK. And so on.
