A couple of people at work have asked me how to get some of the US only features working on Vista Media Center.
I have not put it off for any particular reason, It's just I forgot to do it.
Anyhow, it's easy! Copy the registry file content below into notepad and save it out into a .reg file.
Windows Registry Editor Version 5.00
"Layout Text"="United Kingdom"
Yeah I know it looks like this will set your keyboard into US, it does but we swap the location over so that the US is actualy UK.
You can do this for any country by changing the DLL etc over to your keyboard.
Oh, nearly forgot, make sure you do a Guide Update after doing this (Tasks/Settings/TV/Guide/Get Latest Guide Listings)
