This advice logically (at least in my opinion) makes sense, because say the hard drive that has the original copy of Win7 crashes, and I get a new one which I'll probably have to reinstall Win7 on (although, being the amazing company they are, Dell will probably just recover any data and put it on to a new formatted hard drive for me). However, from other sites/forums I've been on, people have been saying that I can use the same Windows 7 Key on different computers, but only on one at a time, and I must deactivate the first copy before registering it again. On the top left bears the line 'Windows 7 Pro OA' - from the research I've conducted I have come to the conclusion that OA means OEM (someone with experience please confirm), or non-transferable (again, please confirm). Seeing since it's come from Dell, they've saved me the pain of installing Windows 7 myself, and have also handily provided me with a sticker that displays Proof of License and Certificate of Authenticity. Preface: I'm building my own computer from scratch after having headaches with my current one (a Dell) for about 4 years.
