System Restore weight Loss Sanbang

System Restore is one of the most useful features of Windows XP that takes a snapshot to record the system's state information at a given time, known as a "restore point," and then restore it based on that information when needed. There are two types of restore points: one that is created automatically by the system, including system checkpoints and installation restore points, and the other is the user's own creation, also called a manual restore point. As users use the system time increase, restore point will be more and more, resulting in less hard disk space, and finally to be warned that "insufficient disk space", so for "System Restore" to lose weight is very necessary!


First Axe Select the drive to monitor


by default, all drives are automatically monitored unless there is less than 200MB of free space on the drive. But in fact, we just need to monitor the operating system and the drive on which we created the document:


Click start → control Panel → system to switch to the System Restore tab. First select the drive you want to set under the drive window, such as "F", then click the "Settings" button on the right and, in the open window shown in Figure 1, select the check box before "Turn off System Restore on this drive", and the following disk space adjustment slider will turn gray, indicating that the System Restore on that drive "has been closed. When you turn off System Restore on a drive, you can remove the "Volume Information" folder in the root directory of that drive.


If your disk space is tight, but you want to use the System Restore feature, in the window shown in Figure 1, empty the check box before "Turn off System Restore on this drive", and then drag the slider under "Disk space to use" to set the amount of disk space that System Restore takes up.


1. Unless you select "Turn off System Restore on all drives", the drive on which the operating system is located must be monitored, meaning that you cannot only monitor other drives without monitoring the system drives. 2. If disk space is exhausted, System Restore becomes inactive suspend (that is, auto shutdown). System Restore will not automatically activate until enough disk space is available, but all previous restore points will be lost. 3. We can define our own "System Restore" adjustable space size: Click start → run, enter "Regedit" and then return to open Registry Editor. Then expand the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Nt\currentversion\systemrestore Branch in turn, and in the right window you can see two DWORD values "DSMax" and "Dsmin", which represent the maximum and minimum disk space that can be used by System Restore, and modify their key values directly. The branch also has a DWORD named "Diskpercent" that represents the percentage of disk space allocated for System Restore, with a default value of 12%, which we can adjust appropriately as needed.


the second axe to manually delete the restore point


above has said, there is a restore point is the system automatically recorded, since the system is automatically created, it is inevitable to have the time to take the liberty, if you hate windows "unrequited", can completely delete these restore points, but how will not "accidental injury"?


First we need to find the folder where restore points are saved, make sure that show all files and folders is set in Folder Options, and empty the check boxes before the Hide protected operating system files (recommended). At this point you can see that there is a "System Volume Information" folder in each of the monitored drives. 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 called "RPx" and three other files (two of which are configuration files, another file records all of your drive's information, where "X" is a sequential number that represents the total number of restore points, and each folder corresponds to a specific restore point. Obviously, the earliest restore point of time corresponds to the first folder that is "RP1". Now, delete the system-created restore point, just keep what you think is useful!


1. Because "system Volume information" belongs to a system-level folder, you must first log on to the system as Administrator (Super Administrator) before deleting it. 2. When we install some kind of hardware (such as video card) driver, the system will automatically create a restore point in case of failure to return to the original driver, if the driver installed after a period of time the system works properly, then you can delete the system automatically created this restore point.


The third axe only holds the most recent restore points


We can also use Disk Cleanup to keep only the most recent restore points. Right-click the drive letter you want to clean up in Explorer. From the menu that pops up, select Properties → general, click Disk Cleanup, and then switch to the other Options tab from the Open Disk Cleanup dialog box, as shown in Figure 2, click the Clean button under System Restore, Click "Yes" directly in the System pop-up dialog box.


when Windows XP fails to log on correctly, you can go into Safe mode and revert to a previous restore point with System Restore. If Windows


XP encountered a serious system error and could not access safe mode, we can also press the F8 key when Windows XP starts, select Safe Mode with Command


Prompt, and then log in as an administrator and enter%systemroot%\system32\restore\rstrui at the command prompt. EXE, and then follow the on-screen prompts to operate.
