1. The customer can download the Windows 11 pro 64bit English system package, one-click backup and restore tool and system activation tool.

Notice:
(1) Before reinstalling the system, you need to close the anti-virus software, otherwise the “One-click backup and restore tool” will not work.
(2) Before reinstalling the system, please back up important files on the C drive (the C drive will be formatted and deleted after the system is reinstalled)

2. Open the “One-key backup and restore” tool, select the first “One-key reinstall system” menu, and then select the win11 64bit system package to open, as the following figure shows.

3. Restart the computer and decompress the system package, and then install the system automatically (Please plug in the computer, do not operate the computer during the installation process, please wait 10-25 minutes)

4. After the system is installed, activate the Windows 11 system

5. Go to the official website (www.tuner-box.com) to download the Fetrotech Tool software, and then run the installation.

6. After installing the software, open it, copy the ID and serial number of the device according to the prompt, “Ctrl + V” and send it to the seller for activation
