Windows 10 Enterprise Insider Preview with no PS2 keyboard support.

Incredible: Microsoft decides to pull-out default keyboard support for PS2 keyboards (even mouse probably).

 

I just installed Windows 10 Enterprise Insider Preview and I was surprised to discover that PS2 keyboards are no longer supported by default.

Microsoft decides this for us but again doesn't ask the community, this creates problems when new installations are made. In my case I setup the station using an USB keyboard then I give this station to someone else to use, because he doesn't know how to install.
I have legally access to MSDN subscriber downloads if you are wondering ... :)

Anyway the solution for this issue when you have PS2 keyboard on Windows 10 Insider Preview is to download from Microsoft site Microsoft IntelliType Pro

You can use this link: https://www.microsoft.com/en-us/download/details.aspx?id=11105

TIP: You can connect using RDP / TeamView to control the station then you should donwloadn and install the kit above then issue the command : shutdown -r to reboot the station.

Notes: after reboot this Marvell Yukon 88E850 PCI-E Gigabit on ASUS main boards type of chipset remains OFF when it's connected to 1GB switch. You can try downloading latest driver from Marvell site, but in my case the Ethernet Interface remains still OFF after reboot.
