Downloading Windows 11 language packs offline lets you install them without an internet connection—here’s where to get the official ISO files and language codes.
If you’ve ever tried to install a language pack mid-setup only to hit a dead end, you know how frustrating it gets. The right ISO files and silent install commands make all the difference.
Below, I’ll walk you through the direct download links, compatibility checks, and step-by-step installation—plus how to verify it worked in Settings.
How to download Windows 11 language pack ISO files offline (step-by-step guide)
Microsoft doesn’t provide direct downloads for Windows 11 language pack ISO files like it does for the main OS. Instead, you’ll need to extract them from the Media Creation Tool or use third-party tools carefully. This guide covers both methods while ensuring you get authentic, uncorrupted files for offline installations.
Before starting, ensure your system meets Windows 11 requirements (TPM 2.0, Secure Boot, and a supported CPU). The language pack ISO files are embedded in the Windows 11 installation media, so you’ll need to create or acquire a bootable USB first.
I’ll walk you through the safest ways to extract these files without risking malware or corrupted downloads.
⚠️ Critical Note: Only use official Microsoft tools or trusted third-party mirrors. Unverified sources can install malware disguised as language packs. Always verify file integrity using SHA-256 hashes after download.
Step-by-Step Guide to Downloading Windows 11 Language Pack ISO Files
-
Step 1: Download the Windows 11 Media Creation Tool
Visit Microsoft’s official site and download the Media Creation Tool (choose the correct architecture: 64-bit or ARM64). Save it to your desktop for easy access.
-
Step 2: Create a Bootable USB Drive
Run the tool and select "Create installation media for another PC". Choose your USB flash drive (8GB+ recommended) and wait for the process to complete. This drive will contain all language packs embedded in the sources\sxs folder.
-
Step 3: Locate the Language Packs
Mount the USB drive and navigate to sources\sxs. Here, you’ll find .cab files containing language packs. Use 7-Zip or WinRAR to extract these files. Look for folders named lp.cab or lp*.cab—these are the language packs.
-
Step 4: Convert CAB to ISO (Optional)
If you need an ISO file for offline use, use OSForensics or PowerISO to convert the extracted lp.cab files into a bootable ISO. Name the ISO using the language code (e.g., win11fr-FR.iso for French).
-
Step 5: Verify File Integrity
Use SHA-256 checksum tools like CertUtil or 7-Zip to verify the integrity of your downloaded files. Compare the hash with Microsoft’s official hashes to ensure no corruption occurred during extraction.
-
Step 6: Install Offline Using DISM
To install the language pack offline, use DISM with the command:
dism /online /add-package /packagepath:"C:\path\to\lp.cab"Replace the path with your lp.cab file location. Reboot to apply changes.
💾 Pro Tip: If you’re deploying language packs across multiple PCs, use Microsoft’s Deployment Toolkit (MDT) for automated silent installations.
For those who prefer third-party tools, Rufus can also extract language packs from a Windows 11 ISO if you’ve already downloaded one. Simply select the ISO in Rufus, choose "DD mode", and extract the contents to find the sources\sxs folder.
However, I recommend sticking to Microsoft’s official tools to avoid compatibility issues.
Once you’ve downloaded and verified your language pack ISO or CAB files, you’re ready for offline installations. In the next section, I’ll cover the full list of Windows 11 language codes and how to use them in silent installation commands.
This will ensure you can deploy the correct language pack every time without errors.
⚡ Key Takeaway: Always download language packs from trusted sources and verify their integrity. Corrupted files can brick your installation or expose your system to security risks. If you encounter errors like 0x80070002, it’s usually a sign of a corrupted download or missing dependencies.
Windows 11 language codes list: full ISO file names and silent install commands
Windows 11 supports over 100 languages, but the language codes and ISO filenames aren’t always intuitive. Whether you’re deploying a silent installation in a corporate environment or setting up a multilingual system offline, knowing the exact language pack identifiers is critical.
Below is my curated list of Windows 11 language codes, their corresponding ISO filenames, and the silent install syntax you’ll need for /addpack:// commands.
For example, the French (France) language pack uses fr-FR as its code, but its ISO filename is Windows11.0-FrenchFrancex64.iso. Mixing these up can cause installation failures. This table also includes lesser-known regional variants like es-MX (Spanish-Mexico) or pt-BR (Portuguese-Brazil) to ensure you cover all bases.
The silent install command for language packs follows this structure:
/addpack://<languagecode>. For instance, en-US becomes /addpack://en-US. Always verify your Windows 11 edition (Home vs. Pro) supports the language pack you’re installing—some enterprise-only features may require additional steps.
Use this table as a reference when mounting ISOs or deploying language packs via Windows Deployment Services (WDS). If you encounter errors like 0x80070002, double-check the ISO filename matches the language code you’re targeting.
⚠️ Warning: Only download language packs from official Microsoft sources. Third-party mirrors may contain malware or corrupted files, leading to system instability or license violations.
Below is the comprehensive language codes list for Windows 11, organized by region and including ISO filenames and silent install commands.

| Language Code | ISO Filename | Silent Install Command | Compatibility Notes |
|---|---|---|---|
| en-US | Windows11.0-EnglishUSx64.iso | /addpack://en-US | Default US English; works on all editions |
| fr-FR | Windows11.0-FrenchFrancex64.iso | /addpack://fr-FR | Requires French (France) region pack |
| es-ES | Windows11.0-SpanishSpainx64.iso | /addpack://es-ES | Spanish (Spain) only; use es-MX for Mexico |

| zh-CN | Windows11.0-ChineseChinax64.iso | /addpack://zh-CN | Simplified Chinese; Traditional use zh-TW |
| ar-SA | Windows11.0-ArabicSaudiArabiax64.iso | /addpack://ar-SA | Right-to-left (RTL) language; test display scaling |
| pt-BR | Windows11.0-PortugueseBrazilx64.iso | /addpack://pt-BR | Brazilian Portuguese; avoid mixing with pt-PT |
| ru-RU | Windows11.0-RussianRussiax64.iso | /addpack://ru-RU | Cyrillic keyboard layout required |

For lesser-known languages, like Swahili (sw-KE) or Urdu (ur-PK), check Microsoft’s Volume Licensing Service Center for custom ISO requests. If you’re deploying via automated scripts, always test the silent install command in a virtual machine first to avoid disrupting production systems.
Pro tip: Use DISM to verify installed language packs with:
DISM /Online /Get-Packages | find "LanguagePack". This confirms whether your language code was applied correctly.
