"System Restore" is one of the most practical features of Windows XP, it uses the "snapshot" way to record the status information of the system at a specific time, also known as “Restore points& quoquo; and then restore them based on this information when needed. There are two types of restore points: one is automatically created by the system, including system checkpoints and installation restore points; the other is created by the user himself or herself, also called manual restore point. As the user's use of the system time increases, the number of restore points will increase, resulting in less and less hard disk space, and finally be warned "Insufficient disk space", therefore, for "System Restore" is very much weight loss Necessary!

First Step Select Drive Monitor Repair Training for Monitoring
By default, all drives are automatically monitored unless there is less than 200MB of free space on the drive. But in fact, we only need to monitor the operating system and the drive where the documents we created are: Computer Maintenance Forum
Click “Start →Control Panel →System”, Switch to “System Restore&rdquo ;Tab. First select the drive to be set under the “Drive” window, such as “F”, then click the “Settings” button on the right side. In the window shown in Figure 1, open “ The checkbox in the ‘system restore & rsquo;” on the drive, the disk space adjustment slider below will be grayed out, indicating that the system restore on the drive has been closed. When you turn off “System Restore on a drive, you can delete the <quo;System Volume Information” folder in the root directory of the drive.
If your disk space is tight, but you want to use the "system restore" function, you can empty in the window shown in Figure 1, "close the ‘ system restore & rsquo; & rdquo; Before the check box, then use the mouse to drag the slider under "Disk space to use" to set the size of the disk space occupied by "System Restore".
1. Unless you choose "Turn off System Restore on all drives", the drive where the operating system is located must be monitored, which means you can't just monitor other drives without monitoring the system drive.
2. If the disk space is exhausted, “System Restore will become inactive "suspend" "Only System Restore" will be activated automatically only if you have enough disk space, but all previous restore points will be lost. 3. We can define the size of the system by ourselves. Click on “Start →Run” Enter “Regedit” Enter and open the Registry Editor. Then expand the HKEY_LOCAL_MACHINE \\ SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\SystemRestore branch. In the right window, you can see two DWORD values "DSMax" and "DSMin", which represent the maximum and minimum values that can be used for system restore. Disk space, you can directly modify their key values. There is also a DWORD value under the branch called "DiskPercent", which indicates the percentage of disk space to be allocated for system restore. The default value is 12%, which we can adjust as needed.
The second trick to manually delete the restore point
As mentioned above, there is a restore point that is automatically recorded by the system. Since it is automatically created by the system, it is inevitable that there will be self-assertion, if you hate Windows, & rdquo;, these restore points can be deleted, but how can it not "injury"?
First of all, we need to find the folder where the restore point is saved. Please make sure that "All files and folders are displayed" in the "Folder Options" folder, and empty “ hide protected operating system files ( Recommended) & rdquo; checkbox in front. At this point you can see that there is a &#quo;;System Volume Information" folder in each monitored drive. When you open it, you will see a hidden folder with a long name, such as “_restore{299846DD- 6F80-45EF-9DC5-5E2A107D84B1}”. Below are some folders named "RPx" and three other files (two of which are configuration files, and another file records information about all your drives), where “x” is continuous Number, the number of these folders represents the total number of restore points, each folder corresponds to a specific restore point. Obviously, the earliest restore point corresponds to the first folder, “RP1”. Now, delete the restore points created by the system, just keep what you think is useful!
1. Since “System Volume Information” is a system-level folder, you must first log in to the system as Administrator before deleting.
2. When we install some kind of hardware (such as graphics card) driver, the system will automatically create a restore point to return to the original driver when it fails. If the system is working properly after installing the driver, then the system works normally. You can delete this restore point created automatically by the system.
Third move only keep the most recent restore points
We can also use “Disk Cleanup" to keep only the most recent restore points. To do this, right-click on the drive letter you want to clean in the Explorer, select “Properties →General" from the pop-up menu, and then click the "Disk Cleanup" command from the open disk. In the cleanup dialog box, switch to the “Other Options” tab, as shown in Figure 2, click the “Clean up” button in the “System Restore” dialog box, and click “Click” in the pop-up dialog box. Yes & rdquo;
When Windows XP cannot log in normally, you can enter safe mode and then restore to a previous restore point with System Restore. If Windows XP encounters a serious system error, even the security mode can not enter, we can also press F8 when Windows XP starts, select "Safe Mode with Command Prompt", and then log in as an administrator, at the command line At the prompt, type “%systemroot%\\system32\
estore\
strui.exe” and press Enter, then follow the on-screen prompts.
