I just did this a few days ago, on 4/11/2023 to be precise. Everything worked, and the resulting ISO image was written to a flash drive with Rufus and used to install LTSC 2021 on a new computer, no problems whatsoever. I gathered all the files listed by Enthusiast, put them in a directory together with W10UI version 10.25, extracted an original ISO image: en-us_windows_10_enterprise_ltsc_2021_x64_dvd_d289cf96.iso and then had at it. Let me just add a big "Thank You" to Enthusiast for all of his work putting this stuff together for us. Here is the output from running W10UI: Code: ============================================================ Running W10UI v10.25 ============================================================ ============================================================ Extracting .cab files from .msu files... ============================================================ 1/6: windows10.0-kb5012170-x64_47b8ba3bb35c66bbd0631f5425805ccf1dafaf67.msu 2/6: windows10.0-kb5015684-x64_523c039b86ca98f2d818c4e6706e2cc94b634c4a.msu 3/6: windows10.0-kb5020683-x64_119695f48aa3f28a5f68a3dff367957ef8b0f576.msu 4/6: windows10.0-kb5022498-x64-ndp481_c1aab0d4db956163b55ef96eca37af8ad05b102e.msu 5/6: windows10.0-kb5023319-x64-ndp48_381b07db55888307af99f2529ea73ac2bd8ec277.msu 6/6: windows10.0-kb5025221-x64_4cd9fd91665e48fc9a7941376973e2e41c4308e2.msu ============================================================ Extracting files from update cabinets (.cab)... *** This will require some disk space, please be patient *** ============================================================ 1/10: windows10.0-kb5007401-x64_f1bf61d834bb8d9951c7efa23454643daae195b0.cab 2/10: Windows10.0-KB5011048-x64.cab [NetFx] 3/10: Windows10.0-KB5012170-x64_PSFX.cab [SecureBoot] 4/10: Windows10.0-KB5015684-x64_PSFX.cab [Enablement] 5/10: Windows10.0-KB5020683-x64_PSFX.cab 6/10: windows10.0-kb5021043-x64_efa19d2d431c5e782a59daaf2d04d026bb8c8e76.cab [SafeOS DU] 7/10: Windows10.0-KB5022498-x64-NDP481.cab [NetFx] 8/10: Windows10.0-KB5023319-x64-NDP48.cab [NetFx] 9/10: windows10.0-kb5023847-x64_0d515544d250e8d35de07eb37cf84c06284a04aa.cab [Setup DU] 10/10: Windows10.0-KB5025221-x64.cab [Combined] 11/12: Windows10.0-KB5023794-x64_inout.cab [SSU] 12/12: Windows10.0-KB5025221-x64_inout.cab [LCU] ============================================================ Mounting sources\install.wim - index 1/2 ============================================================ Deployment Image Servicing and Management tool Version: 10.0.22621.1 Mounting image [==========================100.0%==========================] The operation completed successfully. ============================================================ Checking Updates... ============================================================ ============================================================ Installing servicing stack update... ============================================================ Deployment Image Servicing and Management tool Version: 10.0.22621.1 Image Version: 10.0.19044.1288 Processing 1 of 1 - Adding package Package_for_ServicingStack_2780~31bf3856ad364e35~amd64~~19041.2780.1.0 [==========================100.0%==========================] The operation completed successfully. ============================================================ Installing updates... ============================================================ Deployment Image Servicing and Management tool Version: 10.0.22621.1 Image Version: 10.0.19044.1288 Processing 1 of 1 - Adding package Package_for_KB5012170~31bf3856ad364e35~amd64~~19041.1880.1.1 [==========================100.0%==========================] The operation completed successfully.

>The whole purpose of LTSC is that it doesn't have feature updates, so it is and will be 19044.xxxx. Thank you . I thought that i remebered that ikb5015684 doesnt realy do anything . For me its just number hunting . My personal question was / is .......... is there a way to get it in / get 19045 into LTSC 2021 ? Not that i realy care . I just wanted to check my memory ...... as i have LTSC 2021 and thought that i remebered haveing it in ..........a memory wich apears to be failing
Have a look at Slimdown10. It removes Edge permanently and much more. It is for Win10 22H2 (19045.x) but should work with 2021 LTSC as well (19044.x): https://forums.mydigitallife.net/th...ws-10-22h2-into-classic-legacy-windows.86552/
Cannot find the wireless display feature in the "optional features" page. Also tried this command "DISM /Online /Add-Capability /CapabilityName:App.WirelessDisplay.Connect~~~~0.0.1.0" My computer supports miracast/wireless projection feature. I tried it on windows 10 home and it worked find. My hypothesis/guess is that ltsc doesn't contain the files so how can i manually install it?
In the Dolby Access app from the Microsoft Store, there are demo videos. On LTSC (newly installed, unmodified), the videos will play but there will be no sound. On Windows Pro (newly installed, unmodified), there is sound. I know it's probably an audio codec missing, but I cannot figure out which one it is. It's not the Dolby Atmos thingy that's missing from LTSC because I installed it and there's still no sound. I'm using the regular LTSC, not the N version. Does anyone know what it could be? EDIT: I installed LTSC N on a virtual machine and installed the Media Feature Pack. Demo videos in Dolby Access app have sound... It seems that regular LTSC doesn't come with all the codecs that are in the Media Feature Pack. The problem is that you cannot install the Media Feature Pack on regular LTSC. Is there a solution to this?
