Makes me so happy to see so many people excited to upgrade to Win10 on day 1, as someone who works in IT support I look forward to being very busy in the coming weeks.
The number of people migrating from perfect OS's into the unknown on Day 1 is fascinating to me, if upgrading from a Home version of 7/8 to windows 10 keep in mind that you are losing the ability to control windows updates completely, if MS want to change your OS you have no say in the matter on Home variants of Win10, just the way that we have a choice right now to migrate from 7/8 > 10, that choice is not going to be a feature of Win10.
My personal advice is not to upgrade until at least the first couple of months to see that there isn't any massive flaws in the OS which will pop up after main stream launch, Could be the best OS to ever exist, but you don't want to be the first ones in the door to find out it isn't if you are running a perfect OS right now.
