In this case the MB was an ASUS with INTEL chipset.Updating some components of an old computer is usually more trouble an effort than the gains you get. Best to get a whole new computer. adding a hard drive is one thing but go with all new instead of replacing half or more of your computer.
And this is the issue with windows vs macs : too many brands/models of windows hardware vs. Apple controlled hardware since they compile and make the entire computer for sale. This is why tablets are more reliable. You can't switch out tablet components that could cause the operating system to not work. To ram or video card to reseat because the connection isn't perfect anymore, etc. Get my point ?
It's not that Microsoft does care, it's that there's too many IBM compatible components out there that I'd then an issue on your end that they cannot be responsible for.
Anyway they should pay back if they decides after 2 monthes to exclude my computer ... because the problem is not that my HW was not supported but that they suddenly decide to not support it anymore : this is really different. The other problem is that there online support is totaly incompetent : they dont understand anything ...
