Windows 10 on any x86 since 2000? Not true. Windows 10 requires PAE, NX, and SSE2; and 64-bit additionally requires CMPXCHG16b, PrefetchW, and LAHF/SAHF. In practice, this means Athlon64 (2003) or Prescott Pentium 4 (2004) or VIA C7 (2005) or later, minus some models due to Intel's insane market segmentation policy or driver issues. Full 64-bit Windows requires a CPU from about 2006. After spending way too much time looking, I'm still not sure which ones.
