How to Create Standalone Offline Installers for Windows 11 24H2 Features
In environments with limited or no internet access, managing Windows 11 feature installations can be a headache. Whether you need RSAT tools, language packs, or other optional features, you can save time and bandwidth by creating a standalone offline installer. Here’s how.
Why Use Offline Installers?
- Works in air-gapped networks or secure facilities
- Speeds up deployments without downloading files on each device
- Ensures consistent feature versions across all machines
- Simplifies bulk installations via USB drives or network shares
Step 1: Download the Languages and Optional Features ISO
Microsoft provides a special ISO for Windows 11 24H2 that includes all optional features and language packs. You’ll need to find and download this ISO so you can mount it and access the feature packages directly.
Step 2: Mount the ISO
- Right-click the ISO file and choose Mount.
- Note the drive letter assigned to the mounted ISO (for example, E:$$.
Inside, you’ll see a folder named LanguagesAndOptionalFeatures containing numerous CAB files and metadata.
Step 3: Prepare Your Offline Source Folder
Create a folder on your local drive or network share, such as C:\OfflineFeatures. Copy the entire LanguagesAndOptionalFeatures directory from the mounted ISO into this folder. This becomes your offline source.
Step 4: Install Features with PowerShell
PowerShell makes it easy to install one or many features:
- List available features: powershell
Get-WindowsCapability -Online -Name RSAT* | Select-Object DisplayName, State
- Install a specific feature from your offline source: powershell
Add-WindowsCapability -Online -Name Rsat.ActiveDirectory.DS-LDS.Tools -Source C:\OfflineFeatures -LimitAccess
- Install all RSAT features in one go: powershell
Get-WindowsCapability -Online -Name RSAT* | ForEach-Object { Add-WindowsCapability -Online -Name $_.Name -Source C:\OfflineFeatures -LimitAccess }
Step 5: Install Features with DISM
If you prefer DISM, use this command pattern:
textDISM.exe /Online /Add-Capability /CapabilityName:Rsat.ActiveDirectory.DS-LDS.Tools~~~~0.0.1.0 /Source:C:\OfflineFeatures /LimitAccess
Replace the capability name with the one you need, and point /Source: to your offline folder.
Tips for Success
- Always match the ISO build version to your installed Windows build.
- Keep your offline source updated if you roll out cumulative feature updates.
- Use network shares to let multiple admins access the same offline source.
- Automate installations with scripts for large-scale deployments.
By using the Languages and Optional Features ISO and these PowerShell or DISM commands, you can streamline Windows 11 24H2 feature installations—no internet required. This approach ensures consistency, saves bandwidth, and simplifies rollouts in offline environments.
