    2021-03 Cumulative Update Preview for Windows 10 Version 21H1 for x64-based Systems (KB5000842)
    ERROR installing error code (0x800f081f)
    How do I install this then if I cant through regular system/updates?
    I don't want to reinstall anything as in Clean Install etc. I just built my PC and every update worked perfect until this one.
    I Disabled my Antivirus also when doing trying this update.

    :)

    Windows 10 version 21H1 reported to be build 19043

    Windows 10 21H1 for desktop will be build 19043, confirming once again that it will be another cumulative style release that sits on top of version 2004. It won't be a full blown OS release.
