    To,

    Microsoft Community

    Hi, this is Gavin. I am currently using Microsoft Windows 10 OS, Version 2004 (OS Build 19041.572).

    I want to currently upgrade to Latest Microsoft Windows 10 OS, Version "20H2". I would like to know as if when is Microsoft expected to launch Version "20H2". Any idea or update on that.

    Can i upgrade right now to Microsoft Windows 10 OS, Version "20H2", if Yes then how???

    Please help.

    Thanks & regards,

    Gavin

    why can't windows os upgrade to 21h1 from 20h2

    Windows 10 Version 21H1 (OS Build 19043.899)

    That, I'm afraid, is the price you pay for installing an Insider build. 21H1 has not been released to the public yet and the Release Preview may still have bugs. You are not the only Insider to see this....

    KB5000842 Windows 10 Insider Beta 19043.906 21H1 and RP 19042.906 20H2 - post #48

    See if any of the suggestions later in that thread will work for you.
