How to Change Base OS Language on Windows 8

My windows 8 was installed from an en-UK DVD. When i come to upgrade it to windows 8.1 i downloaded en-US DVD and the setup make me able only to replace windows 8 with windows 8.1 and not to do an in-place upgrade saving not only data but also apps.

To avoid downloading again the ISO I preferred to switch base OS language of my windows 8 to en-US.

Run this command to check the current Default system UI Language:

DISM /online /get-intl

You can’t change base OS language online…
then boot from Windows 8/8.1 DVD and select “REPAIR your computer”.
Click on Troubleshoot, then Advanced Options and Command Prompt.

Win81_Recovery Win81_RecoveryTrouble Win81_RecoveryAdvance

Run this command for change base OS language:

DISM /image:C:\ /set-uilang:en-US

Deployment Image Servicing and Management tool

    Amazing. Thanks a bunch.
    Need to note that even though my windows is installed on C: – in the repair CMD it was actually mounted as G: – it took me a few minutes to figure out why it wasn’t working.
