Why the System restore point that is set does not work

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

1. There is too little free disk space in the partition that is monitored by System Restore. Make sure that the restore process includes a restore point before System Restore creates a restore operation so that the user can undo the restore process. If you experience a restore failure, make sure that you have enough free disk space in all the partitions that are monitored by System Restore.

2. During the restore process, the restore process will fail if the file that System Restore will replace, move, or delete is locked by a system or some other application. This problem is already in: Windows XP Service Pack 1 is resolved.

3. There may be an incorrect restore point because the file entries in the System Restore file change log are inconsistent with the file entries that System Restore actually backs up or tracks.

4. The computer shuts down normally when System Restore increases the file entries to be tracked in the System Restore file change log. When a file is copied or moved to a restore point directory or to another location in the system, a power disconnect or an abnormal shutdown opportunity destroys the process, resulting in changes to inconsistencies in the log. Similarly, a file entry exists in the change log, but the file itself is corrupted or missing.

5. Changes have been made to files in other operating systems (with dual operating systems). For example, changes are made to a critical application or system file, or a file that is tracked by a system restore is moved from one location to another and logged to another operating system. Because System Restore does not reconcile this change, inconsistencies can occur.

6. Changes are made to the files that are tracked by System Restore in a restore point on a removable drive, and the drive is connected to another computer. For the same reason, System Restore does not reconcile this change. It is important to remember that all restore points are interrelated, so any restore point that was established before the missing or wrong restore point will lose its effect.
