Practical skills: WindowsXP system restores weight loss three measures

& ldquo; system restore & rdquo; 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, that is The so-called "restore point" is then restored 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 move Select a monitored drive

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 document we created is:

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 want to use the & ldquo; System Restore & rdquo; function, as can be In the window shown in Figure 1, clear “ turn off the ‘ system restore & rsquo; & rdquo; check box on the drive, then use the mouse to drag & ldquo; to use the disk space under the slider, set &ldquo ; System Restore& quoquo; The amount of disk space used.

1. Unless you choose "Resume 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 is 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 if there is a self-assertion, if You hate Windows "self-love", you can completely delete these restore points, but how can it not "injury"?

First 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 Operations Check box in front of system file (recommended) & rdquo;. 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. Because System Volume Information is a system-level folder, you must first log in to the system as Administrator before deleting.

2. When we install a certain hardware (such as graphics card) driver, the system will automatically create a restore point in case of failure to return to the original driver, if the driver is installed, run the system for a period of time Normal, then you can delete this restore point automatically created by the system.

The third trick is to keep only 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 can not log in, you can enter safe mode, then use System Restore to restore to a previous Restore points. 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.
