Activating Vista......

I installed vista SP1 and tried many cracks, activators, loader. but none of them worked. Last night i installed a new copy of vista as it was a requirement of some loader/activator. after clean installation, i applied that activator but it didnt worked. :(. Its still giving me 29 days remaining. I have tried each and every thing to activate this but none of em worked or activate the windows. It seems that microsoft is quiet successfull this time. But i will still say that, its really cool, smooth and perfect to handle. If your pc support Vista then dont use any other OS. I am still in hope to find the best solution for this. other wise i have to buy this one.....
