Need help with Windows 8 Developer Preview

hi all,
i clean installed windows developer preview on my pc but my problem is that when ever i try to install nvidia 9400GT drivers(Version-275) in the middle of installation the screen goes blank and never comes back to desktop mode…i checked it in the task manager that the installation is complete but my screen is still blank…then what i did is i re-installed windows DP and used bluepoison 2.1 to unlock the hidden features of windows 8 it changed its appearance from Win 8 to Win 7.now i installed Nvidia Drivers but the Aero effects wont work after the installation..i did troubleshoot for the problem and it showed that Desktop Window Manager is Disabled now i really dont know what that means is there anyway to get Aero Effects and transparency back????
Answer #1
This word explains pretty much everything
Developer Preview
Answer #2
Why would you install it on to your pc?, Use a virtual Macheine.
Answer #3
There are a number of compatibility issues when Win7 drivers are used with the Win8 DP. I had a similar problem when testing the ATI Catalyst package which resulted in the system black screening. It might be possible for you to get this stuff working fully with some hacky changes but to be honest, there is no reason for you to need nVidia drivers on the developer preview. If you want to play games/do something that require those drivers, you should not be using the DP to play them.

yes you are correct there are some hacks which can disable metro UI and make the drivers work i tried it and got it working but didnt like the OS much so installed my Win7 back….thank you guys for your replies
