# Update Windows ISO
|
||
|
||
Official Windows 10 / 11 ISOs available through public free links on [Microsoft](https://www.microsoft.com/en-us/software-download/) or [MSDL](https://msdl.gravesoft.dev/) do not include the latest monthly updates.
|
||
Microsoft usually releases updated ISOs after major feature updates, and the next one typically comes with the following year’s release.
|
||
|
||
These official ISOs work fine for most users since Windows automatically installs cumulative updates (which include all prior updates).
|
||
However, there are several cases where you may need an updated ISO.
|
||
|
||
---
|
||
|
||
## Why You Might Need an Updated ISO
|
||
|
||
### 1. Windows 10 WinRE Update Issue
|
||
|
||
- Microsoft provides official public links for Windows 10 22H2 (Build 19045.2965).
|
||
This build contains an issue that can cause Windows Update to fail when installing [KB5028997](https://support.microsoft.com/topic/kb5028997-instructions-to-manually-resize-your-partition-to-install-the-winre-update-400faa27-9343-461c-ada9-24c8229763bf) on MBR/BIOS installations.
|
||
- Using an updated ISO that includes the latest updates resolves this issue.
|
||
|
||
### 2. Windows 11 LTSC 2024 In-Place Upgrade Issue
|
||
|
||
- The official Windows 11 LTSC 2024 ISOs were released with build **26100.1742**, and Microsoft does **not** provide newer ISOs to MVS paid subscribers.
|
||
- If your Windows 11 LTSC 2024 installation is already updated to a newer build and you attempt an in-place repair upgrade using the 26100.1742 ISO, the process will fail.
|
||
- Using an ISO that includes the latest updates will resolve this issue.
|
||
|
||
> **Note:**
|
||
> The same issue occurs with Windows 11 24H2 GAC editions (non-LTSC). However, since updated ISOs for 25H2 are already available, you can use those instead.
|
||
|
||
### 3. Frequent Windows Installations
|
||
|
||
Technicians or shop owners who install Windows multiple times per day benefit greatly from updated ISOs.
|
||
Using an updated ISO saves both time and bandwidth during setup and post-installation updates.

||
|
||
## How to Get an Updated ISO
|
||
|
||
### Option 1: Updated ISOs from MVS
|
||
|
||
Microsoft provides monthly updated Windows 10 / 11 ISOs (non-LTSC) to [MVS](https://my.visualstudio.com/Downloads) subscribers.
|
||
Alternatively, you can find download links [here](genuine-installation-media).
|
||

|
||
|
||
### Option 2: Manually Update ISOs
|
||
|
||
**Applies to:** Windows 10, Windows 11, and Windows Server 2025, 23H2, 2022
|
||
|
||
:::info
|
||
|
||
- To create an updated **Windows 10** ISO, your host operating system must be **Windows 8.1 or newer**.
|
||
- To create an updated **Windows 11** ISO, your host operating system must be **Windows 10 version 2004 or later**, or **Windows 11**.
|
||
|
||
:::
|
||
|
||
Follow these steps to manually create an updated Windows ISO:
|
||
|
||
1. **Download the base ISO**
|
||
- Get the official ISO from [MSDL](https://msdl.gravesoft.dev/) or [Microsoft](https://www.microsoft.com/en-us/software-download/) (Download ISO file directly; Media Creation Tool ISOs won’t work here.) or [here](genuine-installation-media).
|
||
|
||
2. **Download W10UI**
|
||
- Get [W10UI](https://forums.mydigitallife.net/posts/1216064/).
|
||
Alternative links: [Link 1](https://kutt.it/W10UI) / [Link 2](https://tiny.cc/W10UI).
|
||
|
||
3. **Download Updates**
|
||
- Go to [UUP Dump](https://uupdump.net/).
|
||
(We are using this site here only to fetch official Microsoft update files. Generating ISOs from this site for general use is not recommended; use them for evaluation purposes only.)
|
||
- From the dropdown menu, choose the correct version. For example:
|
||
- For **Windows 10 LTSC 2021**, choose **Windows 10 21H2**
|
||
- For **Windows 11 LTSC 2024**, choose **Windows 11 24H2**
|
||
- For **Windows Server 2025**, choose **Windows 11 24H2** (the update files are the same; the Server 2025 entry doesn’t show the full list)
|
||
- For **Windows Server 2022**, choose **Windows Server 21H2**
|
||
- A list will appear. Select the latest build that **does not include “Cumulative Update”** in its name. It should be labeled “Feature update” or “Windows 10/11.”
|
||
- On the next page, it will ask you to choose a language - no need to change it, just click **Next**.
|
||
- On the following page, it will ask you to choose an edition - again, no need to change anything, just click **Next**.
|
||
- On the final summary page, click the button named **Create download package for these updates**.
|
||
- Extract all the contents of the downloaded ZIP file, then run the script named `uup_download_windows.cmd`.
|
||
- It will download all the update files into a folder named `UUPs`.
|
||
- **Download .NET Updates**
|
||
- The package above includes .NET updates **only** for Windows 11 build 22H2 and newer.
|
||
If you’re updating **Windows 10** or **Server 2022** ISOs, download the .NET updates separately.
|
||
You can skip this step if you’re updating **Windows 11** or **Server 2025** ISOs.
|
||
- Open the appropriate link below based on your ISO version and download the latest month's file.
|
||
- **Windows 10 LTSC 2021 (21H2) / Windows 10 22H2** - [x64](https://www.catalog.update.microsoft.com/Search.aspx?q=3.5+-4.8.1+22H2+1903+Updates+x64) / [x86](https://www.catalog.update.microsoft.com/Search.aspx?q=3.5+-4.8.1+22H2+1903+Updates+-x64+-ARM64) / [ARM64](https://www.catalog.update.microsoft.com/Search.aspx?q=3.5+-4.8.1+22H2+1903+Updates+ARM64)
|
||
- **Windows Server 2022** - [x64](https://www.catalog.update.microsoft.com/Search.aspx?q=3.5+-4.8.1+21H2+Server+Updates)
|
||
- Copy and paste the downloaded file into the same `UUPs` folder where other download files are saved.
|
||
|
||
4. **Mount the ISO**
|
||
- Right-click the downloaded Windows ISO > **Mount**.
|
||
|
||
5. **Set Up the Working Directory**
|
||
- Extract the downloaded W10UI zip file.
|
||
- Create a folder named `Files` on the C or D drive (e.g., `D:\Files`), avoiding spaces or special characters. Make sure you have at least 40-50 GB of free space available.
|
||
- Copy the extracted `W10UI.cmd` file into this folder.
|
||
- Copy all the update files downloaded earlier (from the `UUPs` folder) into this folder.
|
||
Your folder should look like this:
|
||
|
||
|
||
6. **Integrate Updates**
|
||
- Right-click `W10UI.cmd` > **Run as administrator**.
|
||
- Press **1** to select `[1] Target` and enter the mounted ISO drive path (e.g., `H:\`).
|
||
- Press **0** to start the integration process and wait for it to complete.
|
||
|
||
7. **Finish**
|
||
- Once the process finishes, an updated ISO file will be created in the same folder.
|
||
- Done!
