Windows 11 26H2 on a 2008 CPU! (Officially... It Shouldn't Work)

Windows 11 26H2 on a 2008 CPU that, officially, has no business running it. I'm talking about the Intel Core i7-920, launched in late 2008, with zero TPM, zero UEFI, and zero support from Microsoft. I installed it anyway, completely unmodified, straight from a stock ISO. If you caught the last video, you saw Windows 11 23H2 running on a DDR1 motherboard with an AGP GPU. Here it is:    • Running Windows 11 on a 2003 DDR1 Chipset ...   That little experiment actually made the news!!! Yes, it got picked up by Tom’s Hardware and many other tech outlets. This time, we’re going after 26H2. In this video: Why the i7-920 on LGA 1366 X58 is currently the oldest CPU that can technically run the latest Windows 11 Bypassing Secure Boot and TPM checks with 3 registry values (no modified files, no third party tools) Why Windows 11 still fully supports legacy BIOS systems through editions like IoT Enterprise LTSC and Windows Server 2025 The real reason Windows 11 blocks pre-8th Gen Intel and pre-Zen 2 AMD CPUs on paper, but not in practice SSE3, LAHF/SAHF and CMPXCHG16b, and why a handful of 2004-2006 era 64-bit CPUs can't go past Windows 7 SSE4.2 becoming mandatory in Windows 11 24H2, and why that hard blocks Socket 775 and AM3 CPUs for good (AM3+ and Bulldozer FX are fine though) Internal floppy controller support, still alive and well in Windows 11 26H2 Cinebench, games, and general stability testing across the full run #windows11 #intelcorei7 #retropc #techexperiment #lga1366
