Windows 8 has officially been released with new features and improvements. Users who are planning to upgrade from Windows 7 to Windows 8 shouldn’t go by the system requirements given in the official page as many users are receiving “Your PC’s CPU isn’t compatible with Windows 8” error while upgrading to Windows 8. The error occurs when a user tries to upgrade to Windows 8 on a machine that doesn’t support PAE, NX, and SSE2 features.
