Windows restore point does not work

Windows operating system restore point does not work if restored, do you know why? Please see our introduction below.

The possible causes of a restore point failure are as follows:

• There is too little free disk space in the partition being monitored by System Restore. Make sure that the restore process includes System Restore to create a restore point before the restore operation so that the user can undo the restore process. If you are experiencing a restore failure, ensure that there is enough free disk space in the partitions that are being monitored by System Restore.

• During the restore process, if the files that System Restore will replace, move, or delete are locked by the system or some other application, the restore process will fail. This problem has been resolved: Windows XP Service Pack 1 is resolved.

• There may be an incorrect restore point due to a file entry in the System Restore file change log that is inconsistent with the actual backup or traced file entry for System Restore.

• The computer does not shut down gracefully when you add a file item to track to System Restore in the System Restore change log. During a file being copied or moved to a restore point directory or to another location on the system, a power outage or an improper shutdown can disrupt the process, causing inconsistencies in the change log. Similarly, there is a file entry in the change log, but the file itself is corrupted or missing.

• Changes have been made to files in other operating systems (with dual operating systems). For example, changes have been made to critical applications or system files, or a file tracked by System Restore has been moved from one location to another and recorded to another operating system. Since System Restore cannot coordinate this change, an inconsistency can occur.

• The file tracked by System Restore in the restore point on the removable drive has been changed and the drive is connected to another computer. For the same reason, System Restore cannot coordinate this change. It's important to remember that all restore points are interrelated, so any restore points that were created before a lost or incorrect restore point will be useless.
