; : As with previous versions of Windows since
Windows XP, all Windows 10 editions for PC hardware have "N" and "KN" variations in Europe and South Korea that exclude multimedia functionality, in compliance with
antitrust rulings. According to details that Microsoft has published, any app that relies on Microsoft multimedia technologies experiences impaired functionality on these editions, unable to even play audio notification tones. The variation cannot be changed without a clean install, and keys for one variation will not work on other variations. ; : As with Windows 8.1, a reduced-price "Windows 10 with Bing"
SKU is available to
OEMs; it is subsidized by having Microsoft's
Bing search engine set as default, which cannot be changed to a different search engine by OEMs. It is intended primarily for low-cost devices, and is otherwise identical to Windows 10
Home. ; : In some
emerging markets, OEMs preinstall a variation of Windows 10 Home called Single Language without the ability to switch the display language. To change the display language, the user will need to upgrade to the standard editions of Windows 10 Home or Windows 10 Pro. It is otherwise identical to Windows 10 Home. However, it should not be confused with the standard OEM editions of Windows 10, where OEMs and mobile operators can restrict which display languages are preloaded and/or made available for download and installation for their target markets. ; : In May 2017, it was reported that Microsoft, as part of its partnership with
China Electronics Technology Group, created a specially-modified variant of Windows 10
Enterprise ("G") designed for use within branches of the Chinese government. This variant is pre-configured to "remove features that are not needed by Chinese government employees", and allow the use of its internal encryption algorithms. ; : As with Windows 10 Mobile and previous versions of Windows since
Windows Phone 7 for smartphones and
Windows 8 for PCs (since its
mobile counterpart shares the same
Windows NT kernel), device manufacturers (as well as mobile operators for devices with cellular capabilities) who preload Windows 10 can choose not to support certain display languages either during the
OOBE process or available as optional downloads via Settings and/or the Microsoft Store based on the target market. For optional downloads, in the first scenario, the option to download the language pack (and any associated supplementary fonts) will not be available; in the second scenario, the installation will be blocked with the message "This app is not compatible with this device," where the "app" in question is a language pack from the Microsoft Store. Unlike Windows 10 Home Single Language, device manufacturers and mobile operators can support one, some, or even all of the display languages available (though many devices that do not run Single Language editions of Windows will likely support multiple display languages). OEM editions are otherwise identical to their retail counterparts without any other feature restrictions. == Comparison chart ==
