Windows 8 Client and Server: Public developer preview downloads now available

This morning, Microsoft changed everything with the announcement of Windows 8, showing off their latest OS which really is their "biggest bet yet." The company unveilved it's new touch interface, developer tablet PC's and talked about some other new features. 

The developer center is now live, and Windows 8 is now available for download from this link. The vanilla builds for x64 can be obtained here (3.6GB), and x86 is available here (2.8GB). Windows Server 8 developer builds are also available from MSDN for subscribers right now.

Microsoft says that:

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.

There are two types of downloads available of Windows 8. A vanilla install, and a developer tools install. Developer tools installs cannot be "upgrades" and must be clean installs.

The developer tools install (available here, in x64 only) includes:

  • 64-bit Windows Developer Preview
  • Windows SDK for Metro style apps
  • Microsoft Visual Studio 11 Express for Windows Developer Preview
  • Microsoft Expression Blend 5 Developer Preview
  • 28 Metro style apps including the BUILD Conference app

According to Microsoft, the developer preview "works great on the same hardware that powers Vista and 7." The system requirements are:

  • 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
  • 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
  • 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  • DirectX 9 graphics device with WDDM 1.0 or higher driver
  • Taking advantage of touch input requires a screen that supports multi-touch

Many are reporting the downloads to be very slow, however, if you have a MSDN subscription that method is reportedly faster right now.

Interestingly, Windows 8 dev preview expires on 3/11/2012 4:59PM. Does this mean we'll see a beta sooner than we thought?

How are you guys getting it to load in virtual box? It just sits there at the screen with the little circle dot thingie for like 20 minutes now.

Got it installed on a 3rd partition and the boot time is friggin fast even on my old laptop 2.16 ghz Intel Celeron 3GB Ram. Less than 6 seconds boot time, I know it's not complete but it seems more designed for tablets than a productive desktop OS. It would be nice to have it running on my HP TouchPad

Seriously, i have tried to understand this and like it. Trying to look past the almost perfect experience which is windows 7, but SERIOUSLY!?!?!?! This is a pile. In the build video, steve says this is the interface near complete as opposed to the Windows 7 developer release, which did not posses a complete final UI. Windows 8 pretty much makes every single non touch device completely unuseable. I have to scroll forever to move along inside the metro ui. In the classic desktop, if you dont have an application pinned it takes so many clicks and actions to get the program running. Firstly move to bottom corner, click search, click on the apps search button, type in application name, click icon. In Windows 7 this is, open start menu, type application name click icon. The ribbon in explorer is a friggen joke too. In Win7 explorer is so nice and clean. This is a pile of mismatched goals. I have a laptop, and Windows 7 is far more useable to me. Why would i fork out for my laptop to upgrade its OS? Why would anyone with a non tablet device fork out for this? Game over MS. Knee jerk reactions to Appletards buying glowing apple symboled toys are not going to serve you in the long term.

If I install this I can revert back to windows 7?

No, you will be stuck on a pre beta Windows 8 FOREVER, you computer will explode if you try to change the OS...

Well, that is probably what he thought about you when you asked that question. What would ever stop you from reinstalling to another OS if you want to? It's not like an OS can lock down the ability to install another OS.

It took 5 minutes to download on my connection. Perhaps it is because I wasn't going to Download it at 10PM EST when I can't do anything with it right away. I started downloading it today at 5AM.

At least with the 64bit one that comes with the dev tools you need to burn it to a disc or usb stick.. if not it tries to start to install it right on C drive without giving option to install on another hard drive.. so yah just answered my own question.. lol luckily I was paranoid and searched the forums here till I found an answer.. hehe

so I think I shall go invest in some discs and possibly a usb stick with more than 2gb.. *facepalm* heh

bah I don't have a dvd big enough to hold it.. o.O no clue how that is.. lol I got the 64bit dev-tools version.. I have already created a partition for it.. is it possible to mount the iso using a program to install it on the partition that way? or do I need to have it burned to a disc?

In order to burn the Dev. Build ( the bigger one) you need a dual-layer DVD and related player. Otherwise use W7 tools to burn the ISO directly on a bootable memory stick; I would use at least a 4GB memory stick .

I've got a 8 MB/s download speed at the moment! Shame it isn't up on Technet Subscribers' site, only MSDN. But after all, it is primarily for Developers, right?

Try booting the VM with the image and performing the upgrade install from there.

If that doesn't work try VirtualBox.

upgrade from windows 7 in vmware fail upgrade from windows 7 in virtual box working so far 55% installed.

1366 x 768 resolution required for full Metro experience is a disappointment. They should support 1280 x 800 for Metro snap feature.

This preview not being 100% feature complete, we won't come to know what they have decided to completely yank from the OS until a feature complete beta comes around.

metro has got to go in the desktop/non touchscreen versions.

Currently downloading at a steady 2.5MB/s.. about 4 mins in and I'm 44% complete. Thinking of trying to install in VirtualBox. In NY and using Optimum.

I just put this on a dvd and then poured some petrol on it and set it on fire. Its satans problem now.

What a waste of DVD.

Eric Gossett said,
Quick question, Will this let me clean install without the tools version?

I am an hour away from seeing for myself =)

Just burn the image onto an ISO. create a separate partition for Windows 8. boot up from start & chose the new clean partition & presto. once everything is installed, you'll get a nice screen telling you what OS to boot from

installed using virtualbox on my 2011 core i5 imac...install went perfect...video drivers for the guest additions arent working though so im on the tiny screen ...anybody have any ideas to get that working. also to note..i tried forcing the install and restarted and there were no display...i was thinking...aww crap now im gonna have to reinstall it again..tried restarting again using the f5 key and its starts this think called automatic repair...analyses for problems..asks is i would like to restore..i say yes...it goes through the motions and restarts and bam..its working again...Nice! dont know if this is a new feature or what but i like it for sure.

I changed the resolution and it's going fine. Without installing Guest Additions I was able to change it up to 1600x1200.

Hey, how do u make it dual boot? Do you just select an empty partition when you install the Windows 8 Developer Preview?

I'm still considering whether I should just use it as my main OS or do a dual boot

No way as a main OS, do not do it. So to dual boot, make a bootable ISO, and then install to a blank partition and that is it. As for this build I thought there would be an option to go to legacy mode but not in this case. This release seems like it is more targeted to touch screen devices. At this point there is no way I would deploy this in any enterprise. Yea yea I know it is a dev build but lmao wow, come on, do not do this for a desktop OS. It is however quite snappy!

:: Lyon :: said,
Aw... now I'm not so excited anymore to install this lol

Sorry bro, just stating how it is, you should definitely do a dual boot to test it out first, it would totally suck if you had to re deploy all your apps and Win 7 OS.

New dual boot screen

https://www.facebook.com/photo...9555&type=1&theater

Ah hahahaha, worst OS ever, man I know it is not the finished product, this is bad!!! However it is quick...

I think the only things I'm a fan of right now are the new spinner icons, boot screen, and that OS selection screen.

I'm giving Microsoft the benefit of the doubt on this since it's a developer preview... but they really need to tone down the Metro. I do not want to continually switch into there every time I open my start menu. And holy crap do they need to make it easier to shut down. I don't want to hover over the bottom left corner, click settings, go all the way over to the bottom right of the screen, click power, and then shut down. If somebody knows of a better way (outside of ctrl+alt+del or pressing the power button) then let me know.

I have just been using this for the last 45 minutes. SO FRICKEN AWEFUL!!!. Are you kidding me MS. They have completely depricated the last 2 decades of refining the desktop into a super useable productive experience. I want Windows 8 desktop edition not Windows 8 you will have a touch screen edition. I hate it. The UI is inconsistent, the metro ui stuff looks like badly designed web apps by a 5 year old. WOW, now even gnome 3.0 seems like a better idea. I will stick to windows 7 for another 5 years then have a look at how the ecosystem has evolved. Ultimately, people need to do work and this is totally unproductive. All the major OS's have fallen apart to suit the needs of the touch screen fad. Someone please build us a new desktop OS for the desktop, for work.

What part of Developer Preview did you not understand? It's not even a beta yet! What were you expecting, a completed OS? This is why I'm not bothering to download this because I know it's nowhere near finished and still needs alot of work (I'm interested as a consumer not as a developer).

What part do you not understand MS wants tiles and metro in their final build... Bookmark my post and read it and weap. The tiles are here to stay, only hope is on final build they make an option to disable metro and the tiles. Such a waste of work productivity

Where did I say the tiles were not staying? way to assume there! I merely said this is a Developer Preview and is far from finished, so complaining about it now is pointless since MS aren't done with it yet and this preview is ment for developers to play around with.

It is good to complain about it so MS can see what parts to keep and what to remove. But alright buddy you are correct, you did not state anything about the tiles.

They need a taskbar of some sort. Having to go to the right side of the window to see only the previous app running is a joke. Too much work involved. Bring back a nice start menu on the classic desktop and give the metro ui some form of dock or taskbar and we are getting closer to productivity. All of the ideas going into this OS are good but the execution is aweful. Its like the applications list in OSX Lion, or the new left side dock bar in Ubuntu Unity, why the hell are these things necessary? All of these companies are ramming touch screen **** down our throats.

FINISHED DOWNLOADING!!! Yup, that's right. Now I can try out all of the Windows 8 goodness on my laptop.

But first, I need to find a CD lying around here that even has 4.8 GB of storage. MS, why did you make this ISO so huge????

You did not have to download the 4.8GB version if you did not have a DL DVD. The version without Dev Tools was only 3.8.

Yeah.... just realized that lol. Sometimes I can be so oblivious.
I've already started downloading the OTHER version, and the good thing is that I've got pretty good speeds so far. In the time it took me to post this, the download increased by 1%. Looking forward to Windows 8.

Interestingly, Windows 8 dev preview expires on 3/11/2012 4:59PM. Does this mean we'll see a beta sooner than we thought?

Sooner?
Even that is too long for me.

I'm getting just over 800kbs, but it dips down to 500kbs every few minutes.
I'll let it go overnight, if I have to.
I have a 640gb hd just waiting to be used for this to be tested on.

My first download attempt was very slow. I hit the link again and got 1.9mb/s which is about max for me. It was up & down, but I'm burning now.

I'm getting 3.8MB/s here seems tomorrow will be a fun day playing with it

Thank you Microsoft for making the dev preview available to the public usually we have to wait into the beta stages!

I have to agree. Not only that, but it doesn't appear to require a key either, so no issues with key generation like the Windows 7 Beta fiasco.

Yes, it was mentioned at the end of the BUILD.
No Activation, and No Support.

Well it will only let you upgrade from active OS and will not allow you to select a clean install. Boot from bootable media to perform a dual boot install.

It's 9PM and i'm pulling 2.22MB/s No network congestion for me. Came home late too, was thinking the servers would be hammered, finishing the download in another 10minutes here.

I was downloading with my desktop 2.2 dual core and it was only downloading about 100-200,000 per second. with Firefox.
Started my 2.2 dual core laptop and it is downloading about 1.4-1.5 Mbps using Internet Explorer.
Wonder if Microsoft is making other browsers download slower then Internet Explorer?

gotta know weather it's worth re-installing workstation or just using vmware player for now.....

I have virtualbox installed as well I may get to it but aaarrrg I got an appointment tomorrow!!!! noooooooo!

VMWare Player does not support Windows 8. To be able to run the OS in VMWare you'll need to use VMWare Workstation 8 (any previous version is not able to run it).

Can we have a forum thread which involves just the discussions and not the "I'm getting xxxxx speed" or "it's xxxxxx minutes left" ?

Viper550 said,
Wait what, no x86 version with Developer Tools?


Why would they, x86 as an OS is drying out, x64 all the way and it is not like you cannot use x86 apps in x64.

1.9MB download for me, 18 min.... I want someone here to be a guinea pig and install over there current windows 7 and report back results... Who has the balls....

SHoTTa35 said,
It doesn't support upgrading Windows 7 so you can ONLY do clean installs.

Wrong, go read and I have already tested it. Upgrades just fine from Windows 7

What is interesting is it looks like you may be able to upgrade from Windows XP, if this is true this is huge

Can I install this next to my Windows 7 installation on my laptop and will it automaticly offer me to boot in one or the other OS?

You need to install it on another partition and then it should work. Use disk management to split your disk so you can make another partition, then format it, you should be good to go.

Installing :-) (VmWare Workstation... so dunno if this will work)

I suspect given the requirements that the VMWare Tools may still work. If they refuse then try with compatibility mode (they still have it right?). I'll be downloading the 64-bit one tomorrow to install in VMWare as well.

then when i get home, my first ever attempt at dual-booting

greenwizard88 said,
Any word on whether you can dual-boot it with Windows 7?

Yeah should work with no issues, just make another partition and install to that from your current OS, that is as long as you are running, Vista, Windows 7 with same OS version, otherwise if you want to install a x86 ver on a current running x64 you will have to install from bootable media and then select the partition. Then you may have to use BCD edit to get you dual booting.

I'll use VirtualBox if MS Virtual PC fails me. Either should work just fine though and that's how I was planning to use it.

Perseus Prime said,

I used VirtualBox on my Mac with the Windows 7 (64 Bit) preset and it runs without issues (some minor sound glitches, but that's not a huge deal). If it can run on a Mac, then it should run on a PC.

They will show off the number people who downloaded the developer's preview; at some conference or BUILD blog.
