If you install the right software, Windows XP reportedly can run most Windows 7 software too:

That adds various NT 6 APIs and even compatibility modes for various newer versions of Windows up to Windows 11. At a glance, it appears to have support for Vulkan, Direct3D 10 and Direct3D 11 through software rendering, with the option of using WineD3D to get hardware accelerated Direct3D 10 and 11. I assume old WineD3D-PBA binaries run very nicely on that.

Interestingly, the developer suggests that installing graphics drivers from newer versions of Windows might be possible at some point, which I assume would provide native hardware acceleration for newer graphics APIs and support for recent graphics cards:

> WDDM is not impossible, only very hard. Currently initializes and the subsystem runs, but every driver fails to communicate with it's internal hardware due 2000/XP/2003 doesn't have support for MSI/MSI-X interrupt, required to WDDM drivers works;
