[SOLVED] Win8.1 Upgrade - No "Keep Windows settings, personal files, and apps" option

Before

I was met with only two options from the Windows 8.1 upgrade, "Keep Personal Files Only" or "Nothing". Not much of an "upgrade", I went poking around.

For me it turned out that I had been fiddling with localized development a while back and had an old en-GB language pack still installed. There are various references that the Win8.1 upgrade criteria prohibits "cross language" installs.

Apparently a language pack can't be removed from a running Windows instance, it must be "offline". One way is from the CMD.exe of a Windows DVD/USB install boot disc. Tip: Shift-F10.

After :)

To find which language packs are installed ("Language" is case sensitive):

dism /image:c:\ /get-packages | find "Language"

Which output something long like this:

Package Identity : Microsoft-Windows-Client-LanguagePack-Package~31bf3856ad364e35~amd64~en-GB~6.2.9200.16384

To remove the package:

dism /image:c:\ /remove-package /packagename:{long_name_from_above_output}

That ran for a few minutes to completion and when I booted back into my main instance and retried the upgrade, I was met with the new desired option to preserve my applications as well - yay :)
