Following new updates for Windows 10 20H2 and Windows 10 21H1 Microsoft is also rolling out a new Featured Experience Pack, too. Coming in at 120.2212.3530.0, this one is for Insiders in the Beta & Release Preview Channels.
There's nothing major to note with this Feature Experience Pack. Microsoft says it is just improving the reliability of displaying the candidate list for users of the Input Method Editor (IME.) Note that if you're a Windows Insider in the Release Preview Channel, this will be an optional update for you.
Microsoft also says that this update will not be offered to commercial devices in the Release Preview Channel. That's because these devices are getting Windows Feature Experience Packs delivered through “C” Preview releases which then get rolled up into monthly “B” releases.
As always, you'll find this Featured Experience Pack under Windows Update. However, for Windows Insiders in the Release Preview Channel, this will be an optional update for you. Happy downloading, and we remind you that these types of Windows Feature Experience Pack updates are meant to deliver a scoped set of features and improvements outside of a full build.
