Backup, Backup, Backup!
Before proceeding, make sure you back up any important data. Use an external hard drive, cloud storage, or another reliable backup method to ensure your files are safe.
Checking Your PC’s Compatibility
Before diving in, let’s confirm whether your PC is indeed unsupported by Windows 11. You’ll need to check a few key specs.
