The Windows Developer Preview is a pre-beta version of Windows 8 for developers. These downloads include prerelease software that may change without notice. The software is provided as is, and you bear the risk of using it. It may not be stable, operate correctly or work the way the final version of the software will. It should not be used in a production environment. The features and functionality in the prerelease software may not appear in the final version. Some product features and functionality may require advanced or additional hardware, or installation of other software.

But I was trying to install in on VMware Workstation 7.1.4, but was getting the probally new BSOD.

It says:

Your PC ran into a problem that it couldn’t
handle, and now it needs to restart.

You can search for the error online: HAL_INITIALIZATION_FAILED

The same screen came when i tried to install it in VirtualPC. Searching on the internet delivers no solution, probally the search engines databases aren’t updated yet. So next try was in Oracle VM VirtualBox. With succes, the setup is running.

So, now waiting for the setup is ready, to play abit around with the tiles

Update: more solutions, boot it from VHD, more info about VirtualBox settings. Windows Developer Preview: General OS questions.

When it comes to talking about “fundamentals” we want to start with boot time – no feature gets talked about and measured more. We designed Windows 8 so that you shouldn’t have to boot all that often (and we are always going to work on reducing the number of required restarts due to patching running code). But when you do boot we want it to be as fast as possible. This is a very deep topic and we have a lot of folks focused on it. We made a bigger leap in this area with Windows 8 than we have in a long time due in no small part to cooperation across the whole ecosystem. Gabe Aul, a director of program management in Windows, authored this post (a first in what will be a series of posts on fundamentals).

This new fast startup mode will yield benefits on almost all systems, whether they have a spinning HDD or a solid state drive (SSD), but for newer systems with fast SSDs it is downright amazing. Check out the video below to see for yourself:

In my environment I was using a HP ProCurve switch with Multicast Filtering (IGMP) enabled. But I noticed that the Multicast Filtering wasn’t working. The default WDS multicast range is from 239.0.0.1 to 239.0.0.254. But if you look at the manual of the HP ProCurve switch, you’ll see they excluded this range from filtering.

So with this in mind, you go to the WDS Server properties and change the multicast range from 239.0.1.1 to 239.0.1.254, so it wouldn’t be excluded anymore on the switch IGMP filtering. So after testing this, the WDS server stopped DDoS my clients (: For the ones who don’t want to search for this setting on their environment, I’ve made a movie, also available in HD, where you can find this setting (sorry, no mic, so it’s a very quiet movie).

Tested with:
Server OS: Windows Server 2008 R2 SP1
Switch: HP ProCurve 2810-48G (J9022A)
