As of my knowledge cutoff in September 2021, there is no version of Windows called “Windows 12” released by Microsoft. The latest version available at that time was Windows 10. However, if you are experiencing issues with your Windows operating system and need to recover it, you can try the following steps
1. Start by restarting your computer. Sometimes a simple restart can resolve minor issues.
2. If your computer is not booting properly or experiencing errors, you can try accessing the Advanced Startup options. Restart your computer and repeatedly press the F8 key (or another key depending on your computer manufacturer) before the Windows logo appears. This will bring up the Advanced Startup menu where you can choose options such as Startup Repair or System Restore to fix your system.
3. If you are unable to access the Advanced Startup options, you may need to use a Windows installation media or recovery drive. You can create a bookable USB drive or DVD with the Windows installation files and use it to boot your computer. Follow the on-screen instructions to repair or reinstall Windows.
4. If you have a system backup or restore point created earlier, you can use it to recover your system. Access the Advanced Startup options or use a Windows installation media to reach the recovery options, and select the option to restore your system from a backup or restore point.
5. In case you are unable to resolve the issue on your own, it’s recommended to seek professional help or contact Microsoft Support for further assistance.
Please note that these steps are based on the Windows 10 operating system, as there is no official release of Windows 12.
If a new version has been released after my knowledge cutoff, please refer to official Microsoft documentation or contact Microsoft Support for the most up-to-date instructions on recovering your specific version of Windows.
