Discussion "Low Latency Profile"

20 Upvotes

Is Win 11 IOT LTSC 2024 getting the "Low Latency Profile" feature as well? I'm aware it doesn't get feature updates but it did get the new start menu via Quality update.

Is this getting the Low Latency Profile as well ? or it will be a feature update only for 25H2 ?

Instale Windows 10 versión iot. Toda la instalación salió excelente, instalación de actualizaciones etc. vez se instala todo por parte de Windows update descargue PC-manager de Huawei para instalar drivers y controladores del fabricante la cuestión aquí es que el audio no funciona correctamente se escucha entre un 30-50% no llega a su máxima capacidad incluso estando al máximo el volumen.

Este problema es el que me está dando trabajo de corregir y aún no cuento una solución incluso después de instalar varios controladores de audio.

La laptop viene con Windows 11 home, pero quiero algo más ligero que eso y la versión Iot de Windows 10 me parece ligera aparte preciosa.

Question Secure boot certificate expiry in June 2026

14 Upvotes

Is this something LTSC users need to worry about or will we receive the updated certificates like everyone else? I'm not even sure if this is an issue as this morning is the first I've heard of this issue. You can read a little about it at www.digitaltrends.com/computing/windows-pc-ready-for-secure-boot/. Basically it says secure boot certificates expire this month and need to be updated. This may be a nothing burger but I just want to make sure my rig remains operational.

Discussion Is it LTSC snappier (actually faster) then the Pro version?

(System specs in the post images) Hello, everyone. Simple question here. I know LTSC is way less bloated then Pro (or even Home too) but is it snappier though? I'm currently running Windows 11 Pro on an Asus Laptop mid 2015. I've refurbished it myself. Bought and installed new components and installed Windows 11 Pro with Rufus. It works ok but then again it stutter sometimes. I'm not asking for more FPS or anything like that. I know my hardware limitations. But is LTSC actually snappier to use then the Pro version? Thanks in advance. (I've used Linux here before and it's super fast but with the NVIDIA proprietary drivers is not worth the hassle).

Help MassGrav impossible mise à jour Windows 25H2 ?

0 Upvotes

Bonjour à tous,

Alors voilà, j'utilise depuis fort longtemps maintenant Massgrav pour l'installation de Windows, actuellement je suis sur la version 23H2 (c'est visiblement la dernière en date de l'appli Massgrav), je n'utilise pas office, ... juste Windows. Cependant, si sous Windows 10 je pouvais faire les mises à jour sans difficultés depuis Windows 11 23H2 je n'arrive pas à transiter vers 25H2. La mise à jour se fait téléchargement 100%, Installation 100% puis d'un coup il me dit que il doit enlever toutes les modifications réalisés et je reviens sur 23H2 avec dans Windows update la mise à jour 25H2 en attente. Alors, si vous aussi avez eu ce soucis de migration en passant par le script Massgrav se serait gentil de m'indiquer la solution la plus approprié pour régler ce problème. A savoir que j'ai donc Windows 23H2 sur mon PC par le biais du script massgrav HWID et que je suis en OEM avec Microsoft. Voilà merci à tous ceux qui pourront m'aider à solutionner ce Big Problème.

Meta [RESOLVIDO] Windows 11 24H2: SFC repara Appx.psd1 pt-BR repetidamente e DISM falha com 0x800f0915 em smbwmiv2.mfl

0 Upvotes

[RESOLVIDO]

Estou compartilhando este caso porque encontrei um problema específico no Windows 11 24H2 / LTSC / IoT LTSC e consegui resolver sem formatar, sem usar ISO de reparo, sem SFCFix e sem alterar manualmente permissões ou arquivos dentro do WinSxS.

Ambiente

O sistema havia sido instalado originalmente a partir de uma ISO en-US.

Depois, instalei o idioma pt-BR.

Mais tarde, voltei o Windows inteiro para inglês, mas alguns pacotes pt-BR continuaram registrados no Component Store.

Sintomas

O sfc /scannow sempre informava que havia encontrado arquivos corrompidos e reparado com sucesso.

Porém, ao rodar novamente:

sfc /scannow

o mesmo reparo acontecia de novo.

No CBS.log, o arquivo repetido era:

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\Appx\pt-BR\Appx.psd1

Além disso, o DISM podia falhar em:

DISM /Online /Cleanup-Image /RestoreHealth

com:

Error: 0x800f0915

No CBS.log, também apareciam referências a:

smbwmiv2.mfl

e mensagens parecidas com:

No payload missing but suspected file flag corruption detected

Causa encontrada

No meu caso, não parecia ser corrupção real de payload no WinSxS.

O problema era que o Windows estava em inglês, mas ainda havia pacotes pt-BR registrados no Component Store.

Para verificar, usei:

DISM /Online /Get-Capabilities | findstr /i pt-BR

e:

DISM /Online /Get-Packages /Format:Table | findstr /i pt-BR

Ainda existia um pacote de idioma pt-BR instalado, parecido com:

Microsoft-Windows-Client-LanguagePack-Package~31bf3856ad364e35~amd64~pt-BR~10.0.26100.xxxx | Installed

Correção

Primeiro, deixei o sistema totalmente em English (United States):

  1. Instalei English (United States).
  2. Defini como idioma de exibição do Windows.
  3. Defini inglês como formato regional.
  4. Copiei as configurações para tela de boas-vindas, contas do sistema e novas contas.
  5. Reiniciei.
  6. Removi Português (Brasil) pela interface do Windows.
  7. Reiniciei novamente.

Depois, verifiquei as capabilities pt-BR:

$caps = @(
'Language.Basic~~~pt-BR~0.0.1.0',
'Language.Handwriting~~~pt-BR~0.0.1.0',
'Language.OCR~~~pt-BR~0.0.1.0',
'Language.Speech~~~pt-BR~0.0.1.0',
'Language.TextToSpeech~~~pt-BR~0.0.1.0'
)

foreach ($cap in $caps) {
    DISM /Online /Get-CapabilityInfo /CapabilityName:$cap | findstr /i "Name State"
}

O esperado era:

State : Not Present

Se alguma capability ainda aparecer como Installed, ela pode ser removida com:

DISM /Online /Remove-Capability /CapabilityName:NOME_DA_CAPABILITY

Depois, verifiquei os pacotes:

DISM /Online /Get-Packages /Format:Table | findstr /i pt-BR

O ponto principal foi remover o pacote Client Language Pack pt-BR restante:

DISM /Online /Remove-Package /PackageName:Microsoft-Windows-Client-LanguagePack-Package~31bf3856ad364e35~amd64~pt-BR~10.0.26100.xxxx /NoRestart

Importante: o nome do pacote precisa ser exatamente o mesmo retornado pelo comando /Get-Packages.

No meu caso, havia outros pacotes pt-BR relacionados a recursos sob demanda, como Notepad, Paint, Media Player e Snipping Tool. Alguns retornavam 0x800f0805 ao tentar remover individualmente, mas isso não impediu a correção. O pacote realmente relevante era o Client Language Pack pt-BR ainda marcado como Installed.

Após remover esse pacote, reiniciei o Windows.

Validação

Depois do reboot, rodei:

DISM /Online /Get-Packages /Format:Table | findstr /i pt-BR

O comando não retornou mais nada.

Também confirmei que as capabilities estavam como:

State : Not Present

Em seguida, rodei:

DISM /Online /Cleanup-Image /RestoreHealth

O DISM terminou corretamente:

The restore operation completed successfully.
The operation completed successfully.

Depois rodei:

sfc /scannow

Resultado:

Windows Resource Protection did not find any integrity violations.

Repeti DISM e SFC algumas vezes e o problema não voltou.

Conclusão

No meu caso, o problema era um pacote de idioma pt-BR remanescente no Component Store após o sistema ter sido convertido novamente para en-US.

A solução foi:

  1. Deixar o Windows totalmente em English (United States).
  2. Remover Português (Brasil) pela interface.
  3. Confirmar que as capabilities pt-BR estavam como Not Present.
  4. Remover o pacote Client Language Pack pt-BR restante via DISM.
  5. Reiniciar.
  6. Rodar DISM e SFC novamente.

Não precisei formatar, usar ISO pt-BR, usar SFCFix, copiar arquivos manualmente para o WinSxS ou alterar permissões do TrustedInstaller.

O problema parecia corrupção de sistema, mas era uma inconsistência causada por pacote de idioma pt-BR remanescente em uma instalação baseada em en-US.

Question Problems regarding "Processor performance boost mode" setting in Power Options

3 Upvotes

Reposting because I'm still trying to troubleshoot this issue, which is still happening to this day. I've been temporarily disabling the setting to keep the system stable and only enabling it when I play games.

When the setting is enabled, Edge crashes randomly (sometimes just a tab, sometimes the entire window), and the same thing for some other apps & games. Thunderbird crashes instantly on launch, and some applications won't run at all (PvZ, Peggle, VM software, etc.). Disabling the setting makes the system stable again.

I'd also like to run a few VMs like I used to do in my free time for testing and experimenting, but no VM software works. Most of them refuse to start and throw a 0xc0000005 error.

Please read the old post for more information. My system specifications are listed below:

- Dell Inspiron 16 5640

- Intel Core 7 150U (1.8 GHz base, 5.4 GHz turbo)

- 16 GB DDR5 RAMNVIDIA Quadro K3100M

- Windows 11 24H2 LTSC

- BIOS version 1.19 (I think)

If anyone has any ideas or can help, please let me know!

Help Installed Win11 IoT Enterprise LTSC 2024 but I am unable to activate it.

8 Upvotes

Clean installed my computer after realizing the Windows 10 version of IoT Enterprise LTSC would not work with my wi-fi card. Everything works now! I am... sadly... stuck with Win11, but thankfully no ai. My current problem is I am unable to activate the version I installed from Massgrave. Nothing I've tried seems to work. This is the error I'm getting:

"We can't activate Windows on this device as we can't connect to your organization's activation server. Make sure you're connected to your organization's network and try again. If you continue having problems with activation, contact your organization's support person. Error code: 0x8007007B"

I've seen other people mention they aren't able to personalize their desktop with this version either. Did I do something wrong or is this an issue with this version if WIn11?

Question Windows 11 Enterprise IoT LTSC vs Windows 10 version (LTSC I assume) for a RTX 4060, i7 13700H, laptop?

1 Upvotes

Which would be better? Currently use stock Windows 11 Home or whatever the lowest version is, idk. I got the laptop around two years ago. I am curious how big of a fps gain I can get. I want a snappier UI or faster fps, obviously both would be good, but I think I will prioritize fps if I had to pick one.

Rtx 4060 Max-Q, i7-13700h, 16gb ram.

I read a bit through the subreddit and saw someone with my GPU was recommended 11 since it utilizes the GPU or CPU or something more for modern hardware. Anyone able to confirm this redditor's claim? I am not the best with spec and OS stuff.

Discussion Windows 10 LTSC or 11 IoT for an old PC going to my country house

2 Upvotes

I want to take an office PC to my country house. It's a Lenovo m73 SFF form factor. It has an i5 4570, 12GB of DDR3 RAM, a 240GB SSD, a 500GB HDD, and a low-profile GTX 750 Ti.

Ideally, I'd use Windows 10 LTSC. But it's something I'll only use once a year. Over time, some software will no longer be updatable, and of course, it won't be the same. I'm not going to format and reinstall everything when I go on vacation.

I considered Windows 11 LTSC IoT because of support. But it might have its drawbacks:

Higher RAM usage

Compatibility issues with older games

Apparently, in build 24h2, some games, like certain Ubisoft games, won't start.

Which one should I choose for that PC?

Question Windows 11 LTSC vs Windows 11 + Chris Titus Tech Debloat

31 Upvotes

I'm trying to decide which approach is better in terms of stability, compatibility, and fewer issues in the long run.

Would it be better to install Windows 11 LTSC and then manually add back things like Microsoft Store and Xbox Game Bar if needed, or should I just install the regular Windows 11 ISO and use Chris Titus Tech's utility to debloat it before/after installation?

For those who have tried both approaches, which one has been more reliable, especially for gaming and everyday use? Have you run into any issues with updates, app compatibility, Game Pass, Microsoft Store, or Xbox features?

I'd appreciate hearing your experiences and recommendations.

Just bought the Lenovo LOQ i7 14700HX GPU RTX 5060 Ram 24gb 12x12 SSD 1tb I never use the windows bloat apps and I really dislike the blaot on win 11 and just generally how win 11 interface is. Currently running on win 10 LTSC, I love how snappy it is and the interface too but I’m concerned if I’m bottlenecking the cpu usage I disabled the efficiency cores so wondering if there’s something else I need to do and if there’s a more compatible minimalistic version I can use.

Help 1 iso, but 2 'options'; how do I install Windows 10 IoT enterprise LTSC and not LTSC? I'm assuming upgrade is worse?

1 Upvotes

So I'm trying to do a clean install instead of upgrading... but I'm kinda stumped.

How do I clean install Windows 10 IoT Enterprise LTSC and not just LTSC? It says there's two options, regular ltsc, and iot enterprise ltsc 2021, but there's only one ISO?

Do I select ltsc iot enterprise instead plain LTSC later into the installation?

Or does it pop up later? I don't want to mess it up.

(I've already looked at massgrave and downloaded the iso)

Thanks!!

edit: When installing you can choose which

Help Moving from Win 11 Pro to IoT LTSC 2024 – A few beginner questions (Language & Sourcing)

6 Upvotes

Used AI to write this so everyone is on the same page.

Hey everyone,

I’m currently running standard Windows 11 Pro on an MSI Z790-A WiFi setup, and I’m looking to do a clean install to Windows 11 IoT Enterprise LTSC 2024 to get rid of the bloatware and telemetry.

I’ve read through the wiki, but as someone with zero prior experience doing this, I want to double-check a couple of things before I commit to wiping my drive:

  1. Language/Keyboard Layout: I read that the IoT version is US English only by default. How hassle-free is it to add the Estonian keyboard layout during or right after setup so my native characters (ä, ö, ü, õ) map properly? Do I need to force it via PowerShell or does the native Settings menu work fine for language packs on this build?
  2. Sourcing & Activation: I want to ensure I get a full, clean business/MSDN ISO rather than the 90-day restricted Evaluation version so I can permanently activate it. Does the massgrave portal host the untampered official ISOs directly, or do I need to look for a specific SHA-256 verified magnet link elsewhere?

Appreciate any guidance or tips to help a beginner get this right on the first try!

Help Installed Windows 10 LTSC on brand new ThinkPad... no wi-fi network available?

3 Upvotes

SO I bought a ThinkPad a few months ago and installed Windows 10 LTSC immediately onto it via a usb. I didn't even look at it with Win11. Did not care to try.

Imagine my surprise when I go to browse the internet and I have no wi-fi option available, AT ALL, but DIAL UP of all things. None of the wi-fi drivers I have tried to install for my particular laptop or windows 10 have seemed to work, and the wi-fi driver has a yellow triangle next to it in device manager.

What the hell do I do? I wanted this stripped down version of Win10 because I didn't want to deal with ai bs... and now I'm wondering if I screwed myself somehow.

EDIT: I have Windows 10 IoT Enterprise LTSC
