Windows 10 build 20262.1

== Bugs and quirks==
* The update process to this build has a chance of hanging for extended periods of time.
* Live preview doesn't work for pinned site tabs on some machines, a gray window is seen instead of the intended content.
* There's a chance of encountering an error with the error code 0x80070426 when using a Microsoft account to sign into certain apps. If this bug is encountered, it can be usually fixed by restarting the system.
