    I just accidentally wiped my USB external that I had a file that upgraded Win 10 from 1903 to 1909 without installing the entire OS .iso. It has 2 KB files in it that you ran by clicking on a batch file or the likes. Anyone know what I mean and where I can get a copy? I had no luck with google.

    LoL
    Use WHDownloader to download KB4517245 and install it. That's it. No "tricks" required.

    Sorry, forgot, KB4517245 requires SSU(and maybe CU as well) to be installed/integrated before it can be installed/integrated (respectively).
     
  3. i think @uffbros brother you already know that only enablement pack KB4517245 is required to update 18362 to 63.

    you are already an *********** senior member too.

    Nope, you're supposed to know this because everyone knows this as it has been discussed over and over and over again ad nauseam.

    It never was available by update catalog, it is available by UUP or WSUS, links are provided in the 1903/9 updates overview:

    Without full upgrade it's not an upgrade .. just masked as one !
    and that link is the fastest way from 1903-1909.

    Read the info about the fakeness of 1909.

    Your link downloads the Upgrade Assistant, when ran, it most likeley downloads the full ESD file (probably 18363.418) and starts a full unnecessary upgrade.

    lol 20kb file to unlock. Well maybe so but you have to have the rollup patches first .. you still have to upgrade the full way just some have already got it and just need the unlock some don't. also it's something to do with sha2 standard as well... that get's implemented as well.

    As said, when on 18362.32x+, the "upgrade" will be done by the 20kb 1909 Enablement Package. When on <18362.32x, it needs the LCU which bumps it to 18362.32x+ (but with SSU/LCU's you always only need the latest one), so atm it will be bumped to 18362.720 and then the 1909 EP will enable the 1909 features and set the install to show 18363.720 and 1909.
