Make Sure Windows 11 Is Compatible with PC

For laptops or desktops, updating to Windows 11 from Windows 10 is a complete reinstallation of the operating system. So, you should make sure your computer hardware is compatible with the new system. If the PC cannot meet demands, Windows 11 cannot be installed with an error.

  • Storage: 64 GB or larger
  • TPM: Trusted Platform Module (TPM) version 2.0
