This article describes how to perform basic troubleshooting for issues that involve the System Restore utility in Microsoft Windows Millennium Edition. This article contains steps that you can try when System Restore does not work as expected. For example, System Restore may not restore your computer by using a restore point, or you may not be able to create a restore point. This article also contains a list of references to articles that contain instructions and information about how to troubleshoot specific issues.
The System Restore utility in Windows Millennium Edition monitors and records changes that are made to Windows system files and to the registry. The restore points (also known as system checkpoints) are created automatically. With System Restore, you can "roll back" or restore your system to an earlier configuration when your computer was functioning correctly. You can also create your own restore points. Creating restore points may be useful when you are not sure how a change to your computer will affect the overall performance of Windows Millennium Edition. For example, if you do not know how the installation of a new program or device drivers will affect the performance of Windows Millennium Edition, you may want to create a restore point before you complete the installation.

Allocate more disk space for the data store
System Restore uses at least 200 megabytes (MB) of free disk space for the data store. Restore points and system checkpoint files are stored in the _Restore folder (data store). The _Restore folder is located on the drive where Windows Millennium Edition is installed.Notes
- By default, if you do not have sufficient free disk space when Windows is installed, System Restore is turned off. You must turn on System Restore after you free up sufficient disk space.
- If you run out of disk space, System Restore is turned off. When you free up sufficient disk space, System Restore automatically turns on. However, all earlier restore points are lost.
If you suspect that you do not have as many restore points as you should have, increase the available disk space that System Restore can use to save information. To do this, follow these steps:
- Right-click My Computer on your desktop, and then click Properties.
- Click the Performance tab, and then click File System.
- Under System Restore disk space use, move the slider to the right to increase the disk space that is used for System Restore, and then click OK.
- Restart the computer.
Reset the data store
In some cases, you may want to reset the data store. For example, you may want to reset the data store if you cannot restore your computer by using a restore point, or if you cannot successfully create a restore point.
You may want to reset the data store if you suspect that an earlier restore point is corrupted. Restore points build on earlier restore points. If a restore point from an earlier date is corrupted, all subsequent restore points that are created from that date forward are also corrupted. Therefore, you may not be able to restore your computer by using a restore point.
When you reset the data store, the contents of the _Restore folder are deleted, and all the previous restore points and log files are removed. To reset the data store, turn off System Restore, restart your computer, and then turn on System Restore.Important
When you reset the data store, any previous restore points that were present are no longer available. You can only restore your system by using new restore points that you create after System Restore is turned on again.
