Why? Everyone else is supporting XP with no major problems. Meanwhile, MS has the source code for XP, and for some reason can't replicate that success?
It's over 10 year old operating system already. Software has its shelf life. I can't blame them for wanting to not spread their support matrix too wide.
I don't blame them for trying to kill it off. Truly. It's been long enough, especially now that 7 is actually a solid upgrade for nearly every use.
But I do blame them for all the under-handed, customer-spiteful tactics they've used. DirectX 10 on Vista only, though it's almost 100% compatible with DX9 (having 9 report version 10 allows many DX10 games to run). IE9+ on Vista/7 only. It's complete bullshit, through and through, and I see no reason to defend their methods.

The only games with which this will work is games that support DX9 explicitly and, for some reason, disable it. The D3D9 and 10 APIs are completely different. Having worked on an implementation of DX10 for XP, I can say for sure that this is 100% incorrect.
That was my project, and not very well haha. It worked, if you consider a lack of shaders, lighting (IIRC), and other critical things to be "working". Shaders were a PITA for a few reasons, not the least of which being that the D3D10 shader bytecode was completely undocumented. Spent a couple months doing nothing but reversing the bytecode format, and things sort of fell apart after that. All the code's out there, though, as is the complete story of the project and the company around it: http://daeken.com/alky-postmortem
I'm not entirely convinced mimicking anything Microsoft puts out is a good idea, even under the best circumstances. I've lately been getting pretty far into .NET, and the more I see, the more it terrifies me.
I'm on the fence with them supporting XP. One comparison to take into account is Safari's releases have dropped support for an older OS, much less than 10 years, they did change processor architecture though and have less business users to support. Also Microsoft offer free support.
I don't think they are criticising, I think they are making the point that they aren't the only ones who think you can't do hardware acceleration in XP. Whether that statement is true or not is irrelevant.
Whaa?? I'd cut them slack on not supporting XP.
