Korean OS license convert to English but recognized as not genuine

Microsoft support is available for retail versions only, but OEM versions have to be supported by the manufacturer of the laptop. Microsoft does not support the OEM versions. That is the reason why they are cheap compared to retail versions.

If you think you don't need Microsoft support then you better go with OEM route. I myself, prefer OEM as I never needed Microsoft support. (with the excellent support available from forums like Windows Seven Forums and other help from internet )

My question now after reading the articles you have provided is, if I am going to upgrade my OS to Ultimate, definite I can have an English language but i read another issue of geographical location. If I go back to Philippines and update my OS, will it give me another notification for "not genuine OS"? I appreciate your help and others help. By the way my OS version is Windows 7 Home Premium K which the letter K stands for Korean.

If you upgrade to Ultimate then there should be no restrictions on where you are - so far as I know, there are no GeoBlocked versions of Ultimate (but I may be wrong).
You can use any of the 40-odd languages (or even all of them - one at a time<g>) that you can download from Windows Updates at any time in any place.

....will the WAT allow me to use my Korean License in the Philippines? There might be some issues regarding this? And of course I am going to use English language not Tagalog...

You will only need to ensure that the Ultimate you purchase is not Geo-blocked.
How to Tell

The best way to do this is to purchase direct from MS at the MS Store - Microsoft Store Korea
(Note - my Korean is non-existent, so you'll have to check the details yourself<g>)

You're welcome - You learn by asking the question, and we learn by trying to come up with sensible answers (most of the time )
