I currently have a BIG downer against Microsoft as I have two computers running Windows 10, which will no longer be supported after this month. One is a very high spec gaming laptop, that is still fast today despite being nine years old and the other is my wife’s desktop, which again meets the speed requirement but it isn’t dual core. …
I’m not pleased with Microsoft either, but have to acknowledge their right to make a fair profit. Unfortunately, Microsoft have a long history of unfair business practice, some of which cost them billions in fines. However, they can’t be expected to support aging computers forever. Be aware businesses typically plan to replace laptops after 3 years, desktops after 5, and servers after 7.
The problem with older computers and Windows 11 isn’t speed. It’s security and functional shortcomings in the boot process. When power is applied the computer doesn’t jump straight into the operating system. It starts by executing a built-in program, the “Basic Input-Output System”, or BIOS. The BIOS identifies what peripherals are available and passes all necessary technical details information to the operating system. The O/S also “bootstraps” by loading a sequence of short programs, each of which builds to the point, much later, where a login prompt appears.
As the BIOS has issues, it’s being replaced by the “Unified Extensible Firmware Interface” (UEFI). And, because the security of the operating system depends on the firmware, Microsoft decided that Windows 11 would only work with UEFI. Therefore Windows 11 won’t launch on a computer that doesn’t have UEFI. (There may be ways to hack Windows so it does. Are they secure?)
As transition from BIOS to UEFI will take years, recent computers often support both. Worth checking your computer’s firmware settings to see if UEFI is available. If so, the machine may be Windows 11 compatible after all.
UEFI is not simple.
In a domestic installation, BIOS is good enough because we run on a local network protected by the router & ISP from the evils of the internet: we can keep it simple. Corporates have a much bigger problem: their large scale deployments are exposed to much more serious risks. They need UEFI, and because they spend big money, Microsoft, Intel and others respond to their needs. The rest of us are carried along with the tide.
