I have installed windows 7 ultimate-64bit on my laptop; but it asks me activating the windows within the diven time. However, I cannot activate it because it says that the product key is invalid

From your question it is understood that, you have Windows 7 Ultimate operating system that may be installed in the computer or you may be thinking for installing it. So if you have a disc handy for the operating system then, find the product key on it mentioned as in alpha numeric codes.
If the Windows 7 Ultimate operating system is already installed in the computer and you are not aware of the product key or it is asking to activate the product, you need to contact
Microsoft Volume Licensing Activation Center from the link below:

The activation code is actually a key that either comes with a computer on a sticker or on a retail package. No one can give you a key to activate windows unless they want to lose their ability to activate their copy of windows 7. The activation code is only for the computer or retail software it is sold with. There are other ways to activate but they are considered illegal if you do not own an activation code.

On your updates you will be asked for a windows genuine advantage install. You should be asked to activate windows.

Download the activator in piratebay.se.. thank you

If you don't have the key (didn't pay for it) and it's not licensed to your machine, then it would be illegal to give it to you. If you bought it, contact Microsoft about it.

this telling that your operating system is being used by another computer you will need to purchase a legal copy of windows or reinstall the same one but dont turn on automatic updates or oztion.com to purchase a coa key

Buy Windows 8 Activation Key 64bit 32bit
http://www.Genuinewindowkey.com/
of course, the best place to buy a key is ms. i purchased years from ms online store. however, this time, i'd like to share one special experience on http://www.Genuinewindowkey.com/ .
i visit my forum everyday. one day, i found a piece of recommendation from another guy. so i visited this site.
at the beginning, i'm quite skeptical at them. the price is too low.
then i sent many questions to them.
out of my expectation, they replied to me very soon. each question was answered.
at that time, i planned to try the new Windows 8 activation key.
long story short, i purchased a key from them, received it and download links(32bit&64bit) in about one hour. i need 64. and, more important, the key works at the first try.
i sent much feedback to them. in one word, i'm very satisfied with this purchase, and i think, i should pass words to you.
