When downloading updates it finished and said that it failed to install and had to uninstall them. I restarted compuer and then it says in corner my windows is not a genuine product. I went online and verified that it was genuine. It was preloaded on machine thats less that 2 weeks old. I am now downloading the update again. What do I do about the validation problem? I'm not a pro at computers so I hope someone can help me.
