Win7 system backup several methods

5. Method 1: Win7 comes with system backup
Method 2: 1, the activated system, backup these two files, remember the activation serial number (Appdata is a hidden folder)
%systemroot%\\System32\\spp\\tokens\\pkeyconfig\\pkeyconfig.xrm-ms
%systemroot%\\ServiceProfiles\\NetworkService\\AppData\\Roaming\\Microsoft\\SoftwareProtectionPlatform\\tokens.dat
2, the normal method first reinstall the system, do not enter the activation number, do not network
3, find the above two files, right click on the property - security - advanced - owner, modified to administrator, Close the window, then re-select Advanced - Permissions, modify the Amdinistator to full control, so you can delete the
turn off the Software Licensing service, replace the above two files with the backup activation file (if you do not turn off the service, Tokens.dat can not replace the drop)
4, restart the machine, enter the activation number, live a little after a while, look at the computer properties, if activated, you can network 3-1. Open the Software Licensing service, In the run, enter "SLMGR.VBS -ipk *****-*****-*****-*****-*****"
3-2. Prompt activation number After the modification has been successful, restart the machine
5, view the activation status, run "slmgr.vbs -xpr" or "slmgr.vbs -dlv" Method 3: Don't worry, there is always a way to activate

Win7's system maintenance function is very powerful. With Win7's system backup and restore function, you can basically no longer need Ghost! And Win7 is more intelligent, it will automatically create restore points when you install programs or make important changes to the system. This will ensure that you restore your system to the most recent normal state after a system crash. This is also Ghost's biggest disadvantage - many people are Ghost once again no maintenance, and if the time is long, then the system using Ghost recovery will be beyond recognition.

In addition, common system problems can also be repaired with Win7's WinRE function without reinstalling the system. If you still reinstall the problem as before, you can only say that you still don't understand Win7, I believe that everyone will have a new understanding of this article.

First of all, before introducing the detailed backup and restore function of Windows 7, let us introduce the relevant Windows knowledge points.

System Restore Related Knowledge Points

After the system restore, will the program installed after the restore point and the corresponding data be affected?

In fact, after the system restore operation, the application installed after the restore point will not be used, but the documents and data created by the program will not be deleted or modified. And when you choose a restore point, you can see which programs are affected by the restore operation by clicking the "Scan affected programs" button at the bottom right of the screen, so you can be sure.

What is the difference between system restore and system image restore?

Compared to System Restore, the system image is an exact copy of the drive, similar to the recovery files created by Ghost, which we are familiar with. Therefore, when the computer is restored using the system image, a complete restore operation will be performed. All programs, system settings and files in the current system will be replaced by the corresponding files in the system image. This is the biggest difference between the two.

Note: The maintenance function of Win7 needs to enable the backup and restore function of the system. It is strongly recommended to open it. It does not occupy much system resources, and the benefits are many.

General problems Startup repair is more than enough

Win7 system repair function is very smart, and often does not require too much user intervention. For example, due to a small problem caused by illegal shutdown, when the system is started again, it will enter the "Windows Error Recovery" interface, and the cursor will stay on the "Start Windows Normally" option by default and start counting down. Obviously, the system itself has allowed you to start normally, and the problem has been fixed by itself.

In addition, system files that are corrupted due to improper operation or hardware changes or incorrect configuration files may cause the system to fail to start properly. At this point, the system starts up again, and the "Windows Error Recovery" dialog box will also appear. There are two items in the prompt window, and the default will stop at the "Startup Repair (Recommended)" item. Obviously, Win7 wants users to choose the "start repair" option to fix the system.

After testing, if you select "Start Windows normally", the system can start normally. However, this may cause some unpredictable problems, so for the stability of the system, it is recommended that you take a little more time to enable the system's repair function.

After starting the system's "Startup Repair" function, the system will automatically repair it without your operation. If the prompt "Please restart the computer to complete the repair" after the repair is completed, then you can resume normal after restarting. It is. If the prompt "System Repair does not automatically repair this computer", then use a more advanced tool to fix it. What more advanced tools? Don't worry, let's take it easy.

Unable to start system restore to save

If the "start repair" function can not solve the problem, the system still can not start normally, then you need "system restore" to save!

To enable Win7 system restore function, you need to press F8 when the system starts, select "Repair computer" in the system selection menu that appears, press Enter to confirm and follow the prompts to enter the "System Recovery Options" interface. .

In the "System Recovery Options" window, we can see the "Startup Repair", "System Restore", "System Image Recovery", "Windows Memory Diagnostics" and "Command Prompt" five options, directly Select System Restore and follow the prompts to select a restore point and you will be able to complete the restore very quickly. Restart after completion, in general, you can fix problems such as the system can not be started.

Tip: There are two prerequisites for using the System Restore feature: one is that the system partition has the system protection enabled; the other is that the system restore point (manual or automatic) has been created.

System crash image restore rejuvenation

In general, most system failures can be fixed by boot repair and system restore, but if your system is caused by viruses, etc. The system user configuration file is destroyed, then the above method can not do anything, but don't worry, you can use Win7's system image restore function to repair (the method of entering the system image restore is consistent with the operation of entering the system restore).

So how do you determine if you need to enable system image restore? Very simple, if you use the system restore function to fix an error, it means that the system restore can not be repaired, then use the system image restore to fix it.

The specific operation methods and steps are very simple, the user only needs to operate according to the prompts, and will not be described here.

Tip: Similarly, to use the "system image restore" function, you must first create a system image when the system is normal. In addition, after the system image restore operation, the previous personal files will be overwritten by the file when the system image was created! Therefore, if there are important files to be backed up, you can use WinPE to enter the system, and then copy the important personal files in the system partition. .

System partition failure system CD revived

If you are "lucky" enough, the above methods can not save your system (system partition is destroyed), then we must use the ultimate recovery Dafa - Win7 system installation CD or Win7 system repair CD to help!

Start the system with the Win7 system repair CD, and then enter the "system recovery options" on the CD. Here you can select "Restore a computer with a previously created system image" to restore the system image, and the subsequent operations are exactly the same as the system image restore described above. This is because WinRE in the system partition does not work properly due to system partition failure, so the system will automatically call WinRE on the system CD for repair.

In addition, if you suspect that the fault may be related to the memory, you can select the first item, and then click "Next" to enter the "Select Recovery Tool" interface, where you can select "Windows Memory Diagnostics", if the result It indicates that there is no problem with the memory, and it is not too late to select "system image recovery".

Tip: Win7 system installation CD and Win7 system repair CD repair function are in the "system recovery options", the function is exactly the same, but the method is slightly different:

Win7 system installation CD : After the language selection step, click the “Repair Computer” button in the lower left corner to start searching for the installed system, and then enter the “System Recovery Options” operation; Win7 System Repair CD: When the system is normal, use the recorder to create Win7 The system repairs the disc. Compared to the system installation CD, the system repair CD will directly enter the repair interface after booting. You can directly use the system image to restore or select the tool in the "System Repair Options". Therefore, using the Win7 system to repair the CD is faster and easier than using the Win7 installation CD.

Win7 repair, no reloading

Compared to the previous operating system, Win7 has been "smart" a lot. For ordinary users, after the system has a problem, just follow the system prompts to repair it; for users with certain experience and computer foundation, if you can judge where the problem is, you can skip the detection process, directly Select the appropriate repair tool.

Compared with the reinstallation system, the system's repair function can minimize the user's loss and save the time for reinstalling the system and related software, and there is no need to re-set it. It is convenient and efficient. Br>
