Hello Toms hardware community, I am having a very tuff day with My windows operating system, and their customer support. I have called the exactly 9 times and I've been hung up on twice, none of them have been helpful and most of them don't even know what I am trying to say. That's okay though I'm a very patient person so help is greatly appreciated. Now, for my very simple question. A while ago I built my nephew a brand new gaming PC. The parts got screwed due to overheating even though it had just about the best air coolers corsair makes. Now I have built Him a new PC and I was able to recover the SSD that had Windows on it. Now, is that Windows still valid and can I use it on a brand new computer? (Yes, I still have the product key, but no install disc) Thank you!
