Maybe someone should get a Windows Developer Edition and solve this bug ;) .
Those are called "checked builds" and are freely available to students through Microsoft's DreamSpark program. In addition to that you'll need another system running WinDbg (on Windows), and an EHCI USB debug or serial connection (no pci* serial card with mmio, it needs to use io ports).
Most of the issues I've seen so far were somewhat ACPI related (except for one due to a messed up Int10 handler, ie VGABIOS), and I collected some bits and pieces on http://coreboot.org/ACPI. ACPI debugging is _much_ more powerful with checked builds than without, but for other issues the additional asserts, symbols and lower optimization level are useful, too.
However they're of limited use when trying to find issues in the installer, since that (at least up to Win8) is non-"checked" even on checked build media.
