How to reinstall Win8 and keep the system activation status

Step 1: Prepare to recover the media. Extract the install.wim under the sources in the Windows 8 installation image to a folder on the hard disk partition (cannot be placed in the root directory), such as under E:sources. Of course, if you have an installation disk, just plug in the installation CD and skip the second step.

Step 2: Configure the recovery image. In the command prompt that runs as an administrator, type the following command to enter and run, taking care not to drop the spaces.

reagentc /setosimage /path E:sources /index N

Command Explanation: The path after path indicates the path to the folder where the install.wim file is located. The N after the index indicates the index of the system to be restored in the wim image file. Execute the command “dism /get-wiminfo /wimfile:E:sourcesinstall.wim” (without the quotation marks) to view the E:sourcesinstall.wim System image and their respective index numbers. Make sure that the specified image is consistent with the current system version (Professional Edition with Media Center version requires an image with Media Center), otherwise the activation information cannot be retained after reset.

After the operation is successful, execute the reagentc /info command to view the configuration of the recovery image. As shown below:

Step 3: Start recovery. Open the computer settings, as shown below:

Select General--Delete everything and re-install Windows (Start), then the following figure will appear:

Click “Next” .

In the above picture, we select “Only Windows drivers are installed, so only the partition where the system is located will be formatted when restoring, and other partition files will not be affected.

In the above picture, select “ delete only my files & rdquo;, this option is just a simple format partition, the initialization process takes very little time (about 10 minutes). If we are going to transfer the computer to someone else, it is recommended to choose the second option, so that the partition will be erased first in the recovery process so that the original files in the partition are difficult to recover, which will take a long time.

Click “Initialize” to restart the initialization process.

The initialization process takes about 10 minutes. After the completion, it will restart again. After the restart, some hardware driver configuration, user account settings and other operations are required. Once configured, you will be taken to a brand new Windows 8 operating environment.

After the initialization is complete, enter the desktop and check that the Windows activation status is "activated". Execute the reagentc /info command again to find that the configuration information of the recovery image has not changed due to initialization. That is to say, if you want to reinstall it later, you can directly perform the initialization operation (do not delete the install.wim file), and you do not need to reconfigure the recovery image. The so-called "One-click" in the title of the article is the truth.

Finally, I would like to remind everyone that after installing Win7/Win8, you must remember to use the activated backup and restore function of Rubik's Cube Optimization Master to retain the activation information.
