There are several reasons why the computer xp system restore does not work.

The restore point of the Windows operating system does not work if it is restored. Do you know what the reason is? 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 monitored by “System Restore. Make sure that the restore process includes  System Restore  creating a restore point before the restore operation so that the user can undo the restore process. If you are experiencing a restore failure, make sure that there is enough free disk space in the partition that is being monitored by "System Restore". During the restore process, if the files that will be replaced, moved, or deleted are locked by the system or some other application, the restore process will fail. This problem has been solved: Windows XP Service Pack 1 is resolved.

When the file item to be tracked is added to the "System Restore" to the "System Restore" file change log, the computer does not shut down properly and the Windows 7 system downloads. 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. The file has been changed in other operating systems (with dual operating systems). For example, changes have been made to critical applications or system files, or a <system restore" tracked file has been moved from one location to another and recorded to another operating system. Since “system restore" cannot coordinate this change, there will be inconsistencies. The file tracked by the "System Restore" in the restore point on the removable drive was changed and the drive was connected to another computer. The reason is the same as above, & ldquo; System Restore & rdquo; can not 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.
