I have never went through or even heard of the process you are talking about
I have build two pc's using oem versions of Windows 7 and have not had to do any of that or had any issues with this.
All I did was:
1.) Order products
2.) Build PC
3.) Slide in windows install disk
4.) Install windows and enter code from package the disk came with.
5.) Install drivers/chipset, video, ect...
Shouldn't be any more than this
Let me know if you have any questions or concerns. Thanks,
P.S. Here is a simple video on installing W7 OEM (there are many to choose from if you search on youtube)http://www.youtube.com/watch?v=e1W55hYgVjg
Here is also a thread I found on the Evga Forums, this person is basically asking the same question as you. http://www.evga.com/forums/tm.aspx?m=58 ... dows+7+oem
