Windows XP system restore point is missing doubts

Because Windows system restore is very simple and can solve most system failures, many friends like to use this feature. However, when performing a system restore operation, there may be reasons for the failure to complete the restore operation for one reason or another, and some friends are helpless. Yes, some friends think that after creating a system restore point, everything will be fine. In fact, the restore point created is easy to be lost in some cases. When performing "Disk Cleanup", if it is in the program window, "Others" In the "Options" window, click the "Clean up" button in the "System Restore" column, then the system will only retain the restore point that was created last time, and other restore points created previously will be lost. In addition, many friends think that deleting the RPX (in the item "X” is a number" folder in the system disk System_restore{9E994495-CB58-480C-BCD9-7ECD6C95CA2D} directory can delete the restore point created at a certain time (System The Volume Information folder is hidden) and this view is incorrect. Because "System Restore" is a change basic tracking tool, each restore point it creates is a system change that was created after the previous restore point was created, which will reduce disk space waste and improve performance. Therefore, there is a dependency point between all the restore points. If the older RPX folder is deleted, the system changes will be lost when the restore point was created during the system restore, and the system restore cannot be performed correctly. It seems that you have to be careful when cleaning up files and deleting system restore points. Also, be careful when using some of the junk file cleanup features provided by the optimization software. Check to see if the system restore point is included in the scan options. If you have the best option, cancel this option. Also, be aware that all (including recently created) restore points will be cleared when System Restore is temporarily turned off. Therefore, when you re-enable System Restore, it is a good idea to manually create a restore point in the System Restore program. The system will also intelligently delete some old restore points. By default, there is 12% free disk space for storing restore points (as shown). If the saved restore point exceeds this space, the system will use FIFO (first in/first out) storage, ie new The restore point will overwrite the older restore point. In addition, if there is no free space on the disk partition where System Restore is located, System Restore will automatically clear all restore points to free up more disk space, which will result in the loss of system restore points.
