Microsoft says this 8-year-old CPU is crap, but I say otherwise
My brother's CPU isn't supported by Windows 11, but it plays countless modern games without issue. Thanks to Microsoft, I switched the PC to Linux.

Being the most tech-savvy member of the extended family, I'm often the first port of call for support tickets. My brother is the latest to approach with a problem regarding his Windows 10 PC and some memory trouble. The issue turned out to be a dead CMOS battery, causing settings to be lost on power loss, resulting in failed boots and borked Windows installation. We thought, "What a brilliant time to upgrade to Windows 11!" Turns out, the Intel Core i5-7600K isn't supported by Microsoft's latest OS.
