How to install Windows 8.1 Preview in the UK

Andy Vandervell


Windows 8.1

Want to download and install the brand new Windows 8.1 Preview in the UK? Well, you're bang out of luck because in Microsoft's infinite wisdom, the update supports US English, German, French and a bunch of other languages, but not UK English. Ho hum...

But, but... there is a way and we have it. In fact, we've tried it and it works. So here's how it goes...

Step 1: Download and apply US English language pack

There's more to it than this, but you can't skip this step. Use your preferred method to reach the Control Panel - via search works for us - and head to the 'Clock, Language and Region' section and click on 'Language'.

From here, click on 'Add a language'. Search for 'English' and then double click to reveal the various types and select 'English (United States)' from the list to download the language pack.

We could, at this point, insist on writing the rest of this article in US English, but we won't because... well, it's just wrong, isn't it?

Anyway, next you'll need to remove UK English so that US English becomes the primary display laguage.

You'll be asked to reboot your PC at this stage, but before you do...

Step 2: Fiddle about with the registry to make this work

Sigh. We hoped that would be it, but no. No luck.

Next you need to head to Registry Editor. At this point we feel duty bound to point out that anything you mess up at this stage is totally down to you and advanced users need only apply.

Disclaimer out of the way... search for 'regedit' to get there - as an advanced user you really ought to know this.

Once it's loaded, you need to navigate the following menus from the dropdowns on the left:

  • HKey_Local_Machine >>

  • System >>

  • CurrentControlSet >>

  • Control >>

  • Nls >>

  • Language
Once on the Language page, scroll down to the bottom to the entry called 'InstallLanguage'.

Righ-click on the entry and select 'Modify'. Change the number value from 0809 to 0409, which is computer speak for EN-US.

Step 3: Make a cup of tea (and backup your stuff)

The tea is optional, but you do need to restart and then run the update file that you can download from Microsoft's website. Before you do, however, remember to backup anything you don't want to lose. It's good practice when applying an update such as this.

Thanks for that ... once you've installed the upgrade can you install the UK English pack, or will it only run US English?

I believe I read there's no way of reverting back to UK until final release. Shame, I'll have to give it a miss :(

Thanks for this information but what I found is that when you restart after making the registry change, it will revert the key back to 0809. So I found that I could install the update by not restarting after performing step 2.

setting the regedit language line did it for me. It was 0809, made it 0409 (other language already was), didn't reboot(!!!) but ran the preview update MSU file and it works!
Thanks, I'm Dutch, somehow got a UK version of 8.0 and don't like the ISO option (although I did that yesterday and worked like a charm)

find your way around your own windows 8 for changing language and copy your movements on the french version and you will find your way easy
