Wouldn't it be more advisable to wait for Windows 10 RETAIL version as Windows 10 will be the last major OS release?
My pc is running ahem version and I was thinking of getting a cheap W7/W8 OEM license for this Windows 10 upgrade. But as you know, OEM version is tied to the hardware, specifically the motherboard so you won't be able to reactivate your Windows should you upgrade the mobo. As with most pc enthusiasts, we upgrade our motherboards from time to time and this makes sense if we actually purchase the RETAIL version instead so that we can keep upgrading our hardware without limit. And because Windows 10 is going to be the last OS, it would be endless....as long as Microsoft survives

one option is to get new retail keys from garage sales and you're all set.

any idea about the installation of the upcoming windows 10 ? i was told that the installation files is about 3GB... Can i download the files in another computer and transfer it to my laptop ? or i can only download the files with my laptop ?
it's similar to w8.1 installation except for cosmetic changes. imo the best way is to disconnect from the network before install. it will shorten the installation time significantly.
yes you can do that i think. the offline upgrade installer should be available for download when it's ready. this is to overcome issues of users with multiple systems, the offline installer save repeated downloads of the same contents.
