# OSBuild MultiLang

**This guide requires OSDBuilder 19.4.11 or newer**

So how do you solve the problem of upgrading Windows 10 in an organization with multiple Windows 10 System UI Languages without making 5 separate images?

The answer is so stupid simple, and takes about 10 minutes of time

## New-OSBuildMultiLang <a href="#new-osbuildmultilang" id="new-osbuildmultilang"></a>

This new function has a single parameter, CustomName. This is what you will name your new OSBuild. In this example I have used the following command line

```
New-OSBuildMultiLang -CustomName 'HASMUG1904'
```

When prompted, select an OSBuild. Only OSBuilds with Language Packs installed will be displayed. Press OK

If you read the warning, you will understand how this works. A copy of the OSBuild will be made with the CustomName and MultiLang appended at the end. The install.wim will be exported to Temp, and then mounted, so this is non-destructive to your original OSBuild

Then each Language Pack will be set to the defaults, and a new Index will be added to the Install.wim

The Base Language by default is already Index 1, in my case, en-US

And finally everything will complete. The entire process takes about 2 minutes per Language (not including the Base Language as this is already done). In my example with 5 total Languages, it completed in a little over 7 minutes.

## Image Details <a href="#image-details" id="image-details"></a>

The size difference is about 100MB

Get-WindowsImage shows the 5 indexes

## MDT and SCCM ConfigMgr <a href="#mdt-and-sccm-configmgr" id="mdt-and-sccm-configmgr"></a>

Yes, each Index does contain the proper Language information, so when you deploy this OS, make sure you select the right Index
