Windows 8 freezes on MBP while installing applications

Hi,

I have just installed Windows 8 Pro 64bit on my MBP using Bootcamp.

It runs smooth and all the apps work as promised. I even installed Office 2013 without any issues.

But as soon as I start installing larger applications, like Visual Studio 2012 or Windows Phone SDK 8, or Adobe CS6 MC, the system freezes.

I have enabled HYPER-V...

Can anyone please shine some light on this? Am I doing something wrong? Is there something else I need to do?

I really need Windows 8 to develop Windows Phone 8 apps.
