Most laptops do not have to be activated if they came with windows 7 pre-installed on them.
If you installed windows on your laptop from another disk, then you could be mis reading the activation codes.

You might want to try your laptop manufacturer for the correct code if yours is incorrect.

The code is from the manufacturer, My laptop gave me an error that windows is not activated or something so i just put the code in(which is for my version of windows which is Home Premium x64) and it said invalid code

Hello


Just to make sure, the product activation key is 5 sets of 5 letters / numbers that resemble the one below, does the key you are trying to use resemble this?

Activation keys are version specific, a Home Premium key will not activate a Professional version.

If you are saying the characters are the same they are not.

and yes they are 5 sets of 5 letters/number

Call the manufacturer's Tech Support to have them help you activate.

Make sure you are typing the exact characters as it is easy to transpose one.

Did you reinstall? re-install windows 7

Yh I re-installed it and even though I installed the same version of it...the iso used for installing it is different than the one used in the first place

Yh i already created the disc but like i said it's home premium x64 and i reinstalled home premium x64 but the iso is different...idk if the universal disk will work or not but i will try it out

Exactly how is the ISO different?
