Yes, I use tgt with Windows XP (initiator 2.08).
When Windows finds an unknown device and ask you where you see for the
driver. Then you need to tell Windows that you want to do nothing
about the driver.

My Windows shows "IET Virtual Disk" volume in the "Disk Management":
It's Japanese edition but I guess that you see how it can work for me.

Well, iSCSI is one of SCSI transports. It should not be related with
this issue. Windows SCSI stack doesn't recognize IET controller.

Yes, unfortunately. They changed the policy last year. That's really
bad and stupid move in my opinion.
