Windows7 system restore and image file repair method

1. System Restore

Simply put, when installing application software, hardware drivers or system settings, Windows will first record the current system status to form a backup. In the future, if the system is not working properly, the entire system can be restored to the state at the time of backup. This function looks good, but in Windows XP and previous systems, there are not many people who have actually used this function. The reason is: restore needs to be done after system startup —— However, when the system can not When it is most needed to restore at startup, it becomes empty talk because the system cannot be started. To this end, the first thing many computer enthusiasts do after installing the system is to turn off this feature. Over time, many friends and users do not know that this feature exists.

Windows 7 still retains this feature, but I believe that everyone will be reluctant to close it, because it can restore the system by repairing the disc — — completely solve the problem of the first restore after the start.

1) Creation of Restore Points

By default, Windows 7 automatically creates restore points in a timely manner, for example, when installing hardware drivers, when installing some software, and when making important settings to the system. . It can also be created manually. Generally, if you think that some operations may affect the stability and security of the system, such as installing trial software and updating the unofficial driver, you need to manually create a restore point. The specific method is as follows:

A Right-click on the "Start" menu and select the "Properties" command. Next, click “System Protection” from the window that opens. Here, we can observe that the "protect" status of the partition where Windows 7 is installed is "Open", that is, when the restore point is created manually or automatically, the partition is protected. In general, it is sufficient as long as this partition is in a protected state.

B Click the “Create” button, enter the name of the restore point as prompted in the dialog that opens, and click the “Create” button to manually create a restore point.

Note: The name of the restore point should not be entered for convenience. It should have certain mnemonic significance. For example: “XX time is installed XX”, “XX time is configured with XX” and so on. In this way, you can choose a restore point to restore the system.

2) Restore Settings

System Restore is a very important and convenient feature. The biggest advantage is that it will not destroy the user's files, such as my documents, my pictures, my Music, etc. To make it work better, you can make some simple settings.

By default, System Restore only monitors partitions where Windows 7 is installed. If you want to monitor other partitions, click the “Configure" button and select “Restore System Settings and Previously in the dialog that opens. Version of the file”. Here, you can also control the hard disk space occupied by the restore function — — drag the corresponding slider, generally, you can choose about 10c /o.

To turn off System Restore, simply select "Turn off system protection" here.

3) Repairing the system with a restore point

If you obviously feel that the system is not working properly because of an operation, or after a certain time, the system is attacked by malware. Using restore to fix it is definitely a pretty good choice. Repairing your computer with a restore point can be done in the Windows 7 window or by repairing the CD.

4) Under the Windows 7 window

Click on “System Restore” in the dialog box. Next, select an existing restore point and click the “Next” button.

In this step, you must pay attention to the selection of the restore point, because the program installed after the restore point will not run, and some settings that we have manually performed on the system will no longer take effect. To solve this problem, please pay attention to the name of the restore point to distinguish, or click "Scan the affected program" to view, and strive to find a balance between the recovery system and try to ensure that the installed program and settings are effective.

5) Use the repair CD to restore

After booting the computer with the repair CD (including the installation CD, security mode, etc.), click <; System Restore & rdquo; The operation is exactly the same as under the Windows 7 window.

2.Image Repair

Image Repair is one of the new features of Windows 7, and it works like the well-known Ghost. When creating, the entire partition is backed up as an image file, and when it is repaired, the image file is released to the specified hard disk partition.

Creating an image is done under the Windows 7 window, and restoring the system with an image can only be done by repairing the disc. This design concept takes care of both the ease of operation and the applicability. Creating an image is generally performed when the system is working properly. It is not necessary to use a repair disc to implement it, but it is simple and convenient to operate in the system window. In general, image restoration is mainly used to completely repair a damaged system, which is equivalent to re-installation, but the software installed before the image was created and the settings made to the system can be completely preserved. When the system is unable to start, and when it is most needed, the repair CD comes forward effectively to solve the drawbacks that other recovery measures (such as file recovery) cannot be implemented because the system cannot be started.

1) Create an image

Create an image in the Windows 7 window.

A Click on “All Programs →Maintain →Backup or Restore →Create System Image> to run the Backup Wizard in the "Start" menu.

B Choose where to save the backup. You can choose a shared location on a local hard drive or a removable hard drive on a partition, DVD, or LAN.

Tip: To ensure the convenience of recovery, it is recommended to store the backup on the local hard disk. Backups cannot be stored in a partition where Windows 7 is installed. Only other partitions can be selected.

C Select which partitions to back up. By default, the partition where Windows 7 is installed will be selected and cannot be modified. In general, selecting these two partitions is sufficient.

D Confirm. In the next step, it will display the selected partitions to be backed up, the storage location of the backups, etc. in the form of a list. If it is correct, click “Start Backup", otherwise, click the back button in the upper left corner to reset. When completed, a file with the extension VHD is generated.

Tip: Because the partition file size of installing Windows 7 is relatively large, mostly 10GB or above, the backup takes a long time.

E Hide the partition. In this example, the image file is stored in a partition on the local hard disk. To ensure the security of the image file, you can hide this partition. In the "Start" menu, right-click on "Computer" and select the "Manage" command. In the left window of the window that opens, expand “save →disk management”. Then right-click on the backup partition in the right window and select the “Change drive letter and path” command. Click the “Delete” button in the dialog that opens.

Note: This operation will not delete the partition, just delete the partition's drive letter (such as: E drive, F drive), so that it can not be displayed under the "Computer" window. In the future, when you use the image to recover your computer, you can display the partition letter: right-click the partition with the drive letter deleted, select “change the drive letter and path command ”, and then click “Add&rdquo in the dialog box that opens. ; button, then choose one.

2) Repairing a computer with an image

Repairing a computer with an image can only be done by repairing the disc.

A Start the computer with the repair CD and select “Image Repair”.

B Select where to store the image. First, it will recommend a recent backup for us. Remind everyone that unlike the restore point restore, the image is generally only created once, so to directly select its recommended image.

Tip: If the image file is stored on a mobile hard disk or a shared area on the LAN, click on “Advanced” on the recovery screen to make a selection. When specifying a LAN share location, the format of the path is: \\\\shared computer name\\shared folder name.

3) Extracting files from image files

In actual use, you may encounter a situation where the user file is lost due to a misoperation after the image is created, can you not recover? And extract the missing files directly from the image?

According to Microsoft's description of the Windows 7 image file, the image file cannot be used for partial restore, but the author tried to show that some files in the image are It can be extracted, mainly because Windows 7 provides the original ecological support for VHD files

The actual measurement shows that the image file generated when creating the image has the file extension VHD, just by disk manager Loading as a virtual hard disk is fine.
