    I recently installed LTSC 1809 on a potato PC after swapping the HDD for an SSD. (PC originally came with W8/8.1.) I used MAS 1.5 to activate it (HWID). However, 21H2 keeps showing up as a feature update and of course fails. I'm wondering if there's any way to prevent WUSA from retrieving this update. GPO and registry edits don't seem to do anything to stop it. Setting the connection to metered and blacklisting it with wushowhide don't seem to prevent it either. I don't want to disable updates completely, but I'm at a loss as to why this update would even be offered in the first place. (I want to keep it on LTSC 1809 since it's 10 years old and won't benefit from upgrading to LTSC 21H2 anyway.) Any insight would be appreciated.

    Normally, Winodws Update won't push Feature update to any official\reconstructed LTSB(C).

    This is for 17763.1 Non-LTSC to stop Feature update:
    Code:
    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
    "TargetReleaseVersionInfo"="1809"

    I have that set also. It just keeps coming back over and over, downloading the same 36MB and failing. It's not hurting anything - just annoying.

    Is it pure LTSC without 3rd-party tweaks?

    None of these VMware LTSC would receive Feature update:
    Code:
    VMware16-10240-EntS
    VMware16-14393-EntS
    VMware16-17763-EntS
    VMware16-19044-IoTEnterpriseS
    VMware16-22000-IoTEnterpriseS
    VMware16-22622-IoTEnterpriseS
    
    Last hope:
    Run wushowhide.diagcab to hide 21H2 Feature update.

    10 years old? End-of-Service build is recommended.
    Try 15063 (zh-CN)\16299 (zh-CN)\17134 (en-US\zh-CN)\17763 (en-US\zh-CN) EnterpriseG, it won't receive Feature update.

    It's on rails, but it's moderately tweaked (both pre and post installation) to function on low-end hardware. I definitely broke something related to updates; it installs the security updates no problem though. Other than this one issue it seems to work fine. The most likely way out of it is an in-place upgrade repair with an untouched iso. I just can't have it idling at 1.5GB of RAM; a couple of tabs open in FF or Chrome and it will freeze. Oh, well. Thanks for your help and suggestions.

    I did consider EnterpriseG at one point, but LTSC is what I know and I need another language pack besides Chinese or English.

    Stop the wuauserv service, delete everything inside \windows\softwaredistribution, start wuauserv, see what happens

    Yup, did that, too. The update keeps coming back. I can't understand how it's even being offered. I recall something similar when 1903 was released, but that issue resolved itself after a while. I started with the en_windows_10_enterprise_ltsc_2019_x64_dvd_5795bb03.iso, integrated updates, and removed some components with NTLite before installation. I suppose it's possible I got a franken LTSC out of that. (Removal was limited to Defender, OneDrive, Edge, Cortana, and a few more "features" - iso went from 4.2 to 3.5 GB - nothing massive.) DISM.exe /Online /Cleanup-Image /Restorehealth and sfc /scannow didn't reveal anything wrong either - not that running those commands really work well on LTSC 2019 anyway. Dunno.

    Is it not this registry tweak? >>

    Code:
    REM 9 ::: Turn off featured SOFTWARE notifications through Windows Update
    Reg Add   "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" /T REG_DWORD /V "EnableFeaturedSoftware" /D 0 /F
    
    REM 10 ::: Block Auto Download Windows 10 Feature Updates
    rem reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /v "TargetReleaseVersion" /t REG_DWORD /d 1 /f
    rem reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /v "TargetReleaseVersionInfo" /t REG_SZ /d 1809 /f
    rem reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /v "TargetReleaseVersion" /t REG_DWORD /d 1 /f
    rem reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /v "TargetReleaseVersionInfo" /t REG_SZ /d 2004 /f
    
    Or try this, i assume it's from Win7 , maybe it works...No harm done...

    Code:
    REM 9] Prevents Windows Update to include recommended software and featured software
    reg ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update /f /t reg_dword /v enablefeaturedsoftware /d 0
    reg ADD HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update /f /t reg_dword /v includerecommendedupdates /d 0

    I did an in-place upgrade repair using an updated iso, and, so far, the 21H2 feature update hasn't returned.

    Dumb question: when integrating updates to make an up to date iso, is there any difference when using 17763.1 or 17763.316 as base iso? Which is the recommended one? Or it doesn't matter?
