When Microsoft released the Windows 11 Insider preview earlier this summer, it did so with some confusion around minimum system requirements. It quickly reversed course, saying that more people could install the software update than its requirements originally stated so the company could gather more performance on how the OS performed. After a few months of users testing and providing feedback, Microsoft says that, for the most part, its system requirements from June will stand — but there are a few notable changes.

This means that you’ll need a compatible 64-bit processor, 4GB of memory and 64GB of storage, as well as “UEFI secure boot, graphics requirements and TPM 2.0.” For the most part, Microsoft is still requiring an 8th-generation or newer Intel processor, but the company is adding a few 7th-generation Intel options to the supported list, including Intel Core X-series, Xeon W-series and the Intel Core 7820HQ. For the latter, Microsoft will only support “select devices that shipped with modern drivers based on Declarative, Componentized, Hardware Support Apps (DCH) design principles, including Surface Studio 2.”

After working with AMD, Microsoft has declined to include the first generation of AMD Zen processors in its officially supported list. The full list of supported processors can be found here.

There is some good news for people running older hardware, though. According to The Verge, Microsoft won’t prohibit computers running processors on its “supported” list from installing Windows 11 — they just won’t be able to do so through the official Windows update software. You’ll instead have to download a Windows 11 ISO file and install it yourself. The Verge says this method will primarily be for businesses to try Windows 11 and it won’t be publicizing this method to standard users. 

If you’re still wondering whether or not your computer will be able to officially run Windows 11, Microsoft has released an update for its PC Health Check, which was originally giving users some rather vague and unhelpful messages regarding compatibility. The new version should make it much clearer whether your computer is supported and, if not, what it needs to meet the Windows 11 system requirements.
