A month ago, at the end of August, there were reports that Intel and/or Microsoft might limit the upcoming Wi-Fi 7 to Windows 11 and newer. This speculation stems from a leaked Intel document, which does not mention that Wi-Fi 7 supports Windows 10, but clearly states that it supports Windows 11.
Interestingly, Intel seems to have put that speculation to rest as it listed its first Wi-Fi 7 modules (BE200 and BE202) with support for Windows 11 and Windows 10 noted on their spec sheets. However, no further information is mentioned in the spec sheet, and Intel's latest drivers don't support these modules, which means some compatibility-related issues will remain for the time being.
However, although Intel has officially listed Windows 10 on the list of supported operating systems for these devices, it is very likely that full support for Wi-Fi 7 in Windows 10 has not yet been officially launched, just like Wi-Fi 6E. Right off the bat, we know that the BE200 and BE202 won't be able to use Wi-Fi 7's ultra-wide 320MHz channels, as the highest frequency listed is 160MHz on the 6GHz band. This means that these new modules may not be able to support 46Gbps throughput, assuming Intel's spec sheet is correct. The table below shows a comparison between the new Wi-Fi7, Wi-Fi6/6E and Wi-Fi5:
In addition to no mention of 320MHz, it is known that Windows 10 does not support the 6GHz band of Wi-Fi6E, which means that the operating system is unlikely to support 6GHz of Wi-Fi7. The Intel support article states that all Intel Wi-Fi 6E (Gig+) products support the new 6GHz Wi-Fi band. The use of the 6GHz frequency band depends on the support of the Microsoft Windows (Windows 11) operating system.
Meanwhile, an article in the Netgear Knowledge Base (KB) reads:
The 6GHz wireless band was introduced in the WiFi6E standard and is a dedicated band for devices that support WiFi6E and newer standards (including WiFi7 and future WiFi versions).
Microsoft Windows PC must use the latest Windows 11 operating system and have a network adapter and the latest driver that supports 6GHz WiFi installed to access the 6GHz wireless band.
NOTE: Microsoft recently announced that they will not be rolling back 6GHz support to Windows 10. Even if you have a network adapter that supports 6GHz, if your computer is using Windows 10, you will not be able to use 6GHz WiFi until you upgrade to Windows 11.
Strangely enough, there seems to be a way to bypass the 6GHz limit on Windows 10. While Intel claims that the Wi-Fi driver must be 22.70.0 or newer to use 6GHz, older versions of the 22.45.1.1 driver remove this limitation. This unofficial workaround was discovered on the Intel forums by XenuIsWatching.
