Ensure the safety of your files by backing them up using Google Drive, Mega NZ, MediaFire, or by storing them on a USB drive. Afterward, you can proceed to reinstall Windows to version 22H2 and apply the provided playbook. Once your new OS is installed, you can quickly restore all your files from your chosen storage location, whether it's your USB drive, Google Drive, Mega NZ, or MediaFire.
Please keep in mind that I advise against installing Atlas at the moment, as v0.2 has known issues. I suggest waiting for the release of v0.3 before considering its installation.
