Even though Microsoft ended regular support for Windows 7 last month, there are millions of customers who continue to use the OS and plan to stick with it for a while to come. But even without essential security updates, trying to use Windows 7 in 2020 comes with an even bigger roadblock: most modern platforms aren't supported by the OS, which limits upgrades and replacement hardware to badly outdated parts. So, in an effort to continue supporting customers who want to use Windows 7 no matter what, BIOSTAR has found a way to install Windows 7 on its B365 chipset-based motherboards, which opens doors to new Windows 7-powered desktops with Intel's latest-generation CPUs.

Released in 2009, Microsoft Windows 7 does not support a host of technologies supported by the latest platforms, which is why Microsoft cut off new hardware support for Windows 7 starting with AMD’s Ryzen and Intel’s Kaby Lake (7th gen Core) platforms. Reciprocally, neither AMD nor Intel officially support Microsoft’s legacy operating systems with drivers for their latest platforms. As a result, while it's not impossible to install Windows 7 on newer hardware, it's certainly something that is discouraged at multiple levels.
