Windows 11 was released in October 2021. A user upgraded from Windows 10 22H2 to Windows 11 24H2 on a six-year-old HP Omen using an in-place upgrade. They backed up important files using OneDrive, Proton Drive, and a 4 TB external drive. The hardware was checked for compatibility with Windows 11 using Microsoft’s support page and the PC Health Check app. The user decluttered the system using Disk Cleanup and Revo Uninstaller. A system restore point was created for safety before the upgrade. The upgrade was initiated through Settings -> Update & Security -> Windows Update or the Windows 11 Installation Assistant, and it proceeded smoothly, allowing the user to keep files and applications.
