I bought the vista to windows 7 upgrade which is working perfectly now. The download was quite lengthy and it took a couple of attempts to complete. When installing, the installation wasn't quite what was stated but after following the on screen instructions it did install successfully after a couple of attempts, again quite a lengthy process but then these upgrades normally are. I purchased on a Friday and it was all up and running by midday Saturday. Windows updates and security install taking up a lot of the time. Overall I was very pleased with the service although there were some glitches which I managed to work around. A good product and would purchase from Geeks again if they had a product I wanted. Good value for money.
