From what I have seen, if you get the OEM copy of windows from places like Newegg it can only be installed on one computer. So, does this mean that if I install it on my new build and say the motherboard or hdd dies in a week I will have to buy another OEM copy of windows? Becasue if it is tied to that computer then it must be tied to that motherboard in some way right? Or can u reinstall on a new motherboard even if its not the same type? Also, with the oem version can you reformat and reinstall if you need to? Sorry for all the questions this is my first build and the oem copy will save me alot of $$$. Tried to search too btw.
