Hi, Jintack, I think at least the latest QEMU should work for Windows, but I don't really run Windows that frequently. What is the error you've encountered? Have you tried the latest QEMU, or switching Windows versions to try? What I can remember about Windows is that Ladi had fixed a bug for windows-only (8991c460be, "intel_iommu: relax iq tail check on VTD_GCMD_QIE enable", 2017-07-03) but it should be even in 2.10 so I guess it's not the problem you've encountered.
