Play Windows XP system restore and skills

In Windows XP, we can use the system's own "system restore" function to record the changes we made to the system by setting the restore point. When the system fails, use the system restore function. The system can be restored to its pre-change state.

First, the actual system restore function

Before using this feature, make sure that Windows XP has this feature turned on. Right-click on the "My Computer" button and select the "Properties" dialog box to ensure that the "Reset System Restore on all drives" checkbox is unchecked and then ensure that "need to be needed." The restored partition is in the “Monitoring” state.

It should be noted that when creating a system restore point, make sure there is enough free space on the hard disk, otherwise the creation may fail. The method of setting multiple restore points is the same as above, and will not be described here.

3. Restore restore point

It should be noted that since the system will automatically restart after the restore point is restored, it is recommended that you quit all currently running programs to prevent important files from being lost.

Second, the system restore function advanced operation

1. Setting up system restore

The system restore function takes up a lot of hard disk space, and you can use the “Settings" function to ensure hard disk space. To cancel the "System Restore" feature, simply follow the instructions above, uncheck the "Resume System Restore on all drives" checkbox (Figure 5), delete the system restore point, and free up hard drive space. If you only want to restore the settings of a disk, deselect the "Close System Restore on all drives" check box, select the required partition in the "Available drives" item, click "Settings", select “ Turn off System Restore on this drive to disable system restore for this partition. In addition, you can also limit the disk space used by the partition to restore the function. Select the partition to be set, and click “Set” to drag the block in the pop-up settings window to adjust the space size (Figure 6).

2. Freeing Extra Restore Points

Windows XP restore points include automatic system creation and user manual creation of restore points. When the usage time is lengthened, the restore point will increase and the hard disk space will be reduced. At this time, the extra restore point can be released. Open “My Computer”, select the disk and right click, select “Properties"properties"General”, click “Disk Cleanup> (Figure 7), select “Other Options” Card (Figure 8), in the "System Restore" item click "Clean" button, click Y.

3. System Restore Function Failure Processing

The system restore function mentioned above is operated in Windows XP. If you cannot enter Windows XP system, you can solve it as follows:

(1) Security mode Run System Restore

If Windows XP can enter safe mode, you can perform system recovery in safe mode, the same steps as  Restore Restore Points”.

(2) DOS mode for system restore

If the system can not enter the safe mode, press F8 at startup, select "Safe Mode with Command Prompt", log in as an administrator, Go to the %systemroot%\\windowssystem32restore directory, find the rstrui file, run the rstrui file directly, and follow the prompts.

(3) System Restore in the case of missing restore points

The System Volume Information folder is preset in Windows XP, which is usually hidden, which saves the backup information of the system restore. . Open the View “ Show All Files and Folders property, cancel “hide protected system files> before selecting, you will see the “System Volume Information” folder on each disk (Figure 9). Use this folder for data recovery.

Right click on the "My Computer" button, select "Attributes" & //////////////////////////////////Click the "Apply" button. This is done to rebuild a restore point. Then open the “System Restore” command to find the missing restore point.

The above description is for the FAT32 partition. If the system partition is NTFS, you will have a little trouble starting the System Volume Information folder. Because you may not have been added to the System Volume Information security properties, you will not be able to access the file. Right click on the folder, select “ldquo;property” in the pop-up menu, open the System Volume Information property dialog box, select the “Security” tab, click the “Add” button to open the “Select User” Or group” window, click the “Advanced” button in the lower right corner of the window, then click the “Find Now” button to list all users and groups on the computer and select your current account or account. After the name of the group, & ldquo; determine & rdquo;. The selected account is added to the System Volume Information security properties and the folder is accessible.

4. Customize “System Restore"Space Size

By default, Windows XP uses up to 12% of the space for System Restore, but you can change this by modifying the registry. Run the Registry Editor, and then expand the HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionSystemRestore branch. In the right window, you can see two DWORD values ​​"DSMax" and "DSMin" (Figure 10), which represent the maximum and minimum disk space of the system restore, directly modified. Their key values ​​are fine. 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.
