Finally, Windows 8.1 preview is released on last month and we can test it in our virtual platforms. I want to deploy Windows 8.1 for our Call Center users because Windows 8 has lower IOPS compare to Windows 7. Also it has very faster start-up compare to earlier versions.
I had poor performance with USB controller on this version of Windows. xHCI controller (USB 3.0) is default controller for Windows 8.
I found solution on VMware KB2057809 and if you are facing with same issue, You should remove current controller and replace it with EHCI+UHCI controller.
