    I read about the LTSC version of Windows and fancied to try it because im fed up of the aggrevating bloat, ads and other junk that is bundled with consumer deployments. I'm moving from 7.

    I managed to DL and install (on VitualBox) Windows 10 2019 LTSC using the SVFtoISO tool (bit of a guessing game, I selected LTSC19_2_VLSC which downloaded the EVAL version as below:

    13:15:46 Language: en-gb
    13:15:46 ISO Name: SW_DVD5_WIN_ENT_LTSC_2019_64-bit_English_International_MLF_X21-96427
    13:15:46 ISO Hash: dad202319f78e8e0549966eaf8e57d54b1e7cb8f
    13:15:46 EVAL Name: 17763.107.101029-1455.rs5_release_svc_refresh_CLIENT_LTSC_EVAL_x64FRE_en-us
    13:15:46 EVAL Hash: 369e645a197bc2ca8309cb80467a85a16eacd1a7

    And then converted to ISO with the following results:


    I read about some deletion bugs but figured that I have the latest version of LTSC 2019. To check, I have the below info on the converted ISO:

    The operation completed successfully.
    Is there a way for me to check the ISO SHA-1 against an official list to make sure it has not been modified in any way?

    Excuse my ignorance. I have to be honest that I barely understand the above processes and it did take me a while to figure out how to get to the working ISO. Possible thanks to resources on this forum.

    Does the above look OK to you?

    Since msft blocked non MSDN/MVS subscribers from the info, there are no official methods. @mkuba50 publishes all MVS checksums in every official build thread, links can be found at the OP of every official build thread. And he has a dedicated MVS Dump thread:

    MSFT pulled 17763.1 because of the personal files deletion that could happen in some upgrade scenario's, they replaced it with the Oct. Refresh ISO's (17763.107).

    For LTSC, the 17763.107 is the most current official build.
