How to Upgrade to Windows 11 and What to Expect After Windows 10 Ends

Many Windows 10 PCs, even those marked as incompatible, can be upgraded to Windows 11 for free by adjusting settings like Secure Boot and TPM in the BIOS, often without needing new hardware. The process involves checking compatibility with Microsoft's PC Health Check app, enabling UEFI, Secure Boot, and TPM in BIOS, and possibly modifying registry settings for older hardware. If hardware isn't compatible, adding TPM modules might be an option, but older systems may require replacement. Upgrading is recommended for security reasons, especially as support for Windows 10 ends.
