So i was browsing on xpforums.com and i found a thread <link> . Ok i downloaded and installed it on my PC and i opened dxdiag and i see this:
It's saying DirectX 11.0 (also its saying the os is Windows 7 Pro,but the build number is XP's 
)
I dont know will directX 11 games run since i don't have any samples to test it
