Those reasons for inventory restore point failure

A friend told Xiaobian that when the computer restarted, "System restore was unsuccessful, there was no change to your computer", how to solve this problem? In this regard, Xiaobian consulted the relevant professional People, and forward the answer of the professionals, the specifics are as follows.
Windows operating system restore point does not work if restored, mainly caused by the following reasons, respectively:
1. by < ; System Restore & rdquo; There is too little free disk space in the monitored partition. 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".
2. During the restore process, if the file to be replaced, moved or deleted is 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.
3. There may be a wrong restore point, which is caused by the inconsistency between the file entries in the "System Restore" file change log and the "system restore" or the actual backup or trace file entries.
4. In the "System Restore" to the "System Restore" file change log to increase the file items to be tracked when the computer does not shut down properly. 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.
5. 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 <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.
6. Changed the file tracked in the restore point on the removable drive and connected the drive 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.
The Windows XP operating system's built-in "System Restore" function is very useful, you can use this function to restore the damaged system to its original normal state. If it doesn't work, you can use the above method, hoping to help you solve your problem better.
