Windows 7: This copy of windows is not genuine

I got this message on the right bottom of my screen and when I go to computer properties I see this :



and that's not my OEM product key! I don't know why it change itself??

Edit OEM product ID!

That's not your OEM Product Key, that's your Product ID. If you happen to have a genuine product key, Click Change product key and enter it, that will solve the problem.

I'm using laptop and this was a gift from my uncle from other country? is there other way to activate OS ?

Do you see a sticker at the back of the laptop? It usually contains the Product Key for the default OS installed.

i only see model, express service tag. there is no product key ?

Open the lid enclosing the battery and have a look under the battery as some manufacturers put the product key sticker under it.

The product key consists of five groups of five letters and is different from the product ID.

The product key is used to make sure your system is legal while the product ID tells you whether you have a retail or OEM version of Windows.

You say your computer was bought in a different country. Which one?

I'm just a bit concerned that you are being asked to activate an OEM operating system as it should have been activated by the manufacturer's volume license before the laptop left the factory.

Who manufactured your computer?

It was bought from Norway, and I'm using it here at philippines.

Dell, Inspiron 1545.

Does it come with a Recovery Disk?

Nope.

I found the product key.. and try to put product key but a message says that the windows edition was not belong to the product key...

before my os was Home prem and now it is ultimate due to reformat by a technician.
