Also, you have a 4 core host so don't assign more than 2 CPU cores to the VM, as host PCs like to run with more than 0 cores.

Thanks for your feedback

I changed the VM machine to use 2 cores and now it reached the Windows initial screen after more the 5 minutes but it is too slow .

Any ideas_

Best regards and thanks agaian
