PC went funny [deleted on startup all backups + constant Freeze ups] so 3 weeks ago had to reformat.. Clean install........ now cannot find Thai, or how to set it..

I have genuine Windows 7, before the re-format, I had on the bottom toolbar EN click on this it showed I had English UK + English US + Thai... Now there is nothing ?

When I installed Win 7 I added the Thai Language + since then have gone to updates and installed Thai Language + have downloaded Thai Language form the internet. Nothing is showing, is there a setting somewhere ? as cannot yet find it.

All my Documents in Thai, still are fine and in Thai, but if I try to update anything in a Document then cannot as no Thai font setting changer ?

For year has also been able to change Interface by pressing the button before 1, on XP + Vista + Win 7.. dose not do anything now

I am getting old I'm sure it is something simple just cannot figure it out

Thanks in advance
