Windows 8 build 7955 has leaked

Windows 8 build 7955 has been leaked. The information comes from betaarchive.com who previously leaked the build 7850. As with the previous build, this build is again on a private FTP but is expected to leak publicly in the same fashion as the previous build. 

Much like the previous leak, it is currently on a private FTP but is expected to be posted publicly in the next few hours. The build 7955 is a pre-M3 build but contains more features than the previous build that leaked, 7850. The file weighs in at 2.47 GB. Betaarchive states:

Afternoon all,

We have another leak! Anonymous again as you can expect. This could be the one you've all been waiting for.

Microsoft Windows 8 (''Windows 8'' 6.2.7955.0) (Ultimate) (m2)
ISO Size: 2.47GB (2,657,079,296 bytes)
ISO MD5: 40861A02CB14B0D2D7930910DB6CC6E4

It is now available on the FTP Enjoy!

Notes provided by the leaker:
You can unlock the following:
- Ribbon UI
- Application Folder (now working, in 7850 it was broken)
- Full DWM (hideblur)

The following requires the ''red pill'':
- Webcam
- Login (that ugly guy with ctrl+alt+del, the fishy wallpaper, pattern login)
- TaskUI (new taskmanager)
- PDF Reader
- Immersive Browser

Previously, Neowin has covered information that leaked out from build 7955 which can be viewed here. As this is a later build, it is expected that users will be able to unlock features that have previously not been seen. 

Windows 8 is far off from public availability and it is rumored that a public beta may be announced at PDC later this year. It is expected that Microsoft will launch Windows 8 in late 2012 with the latest rumors suggesting that retail availability will happen in early 2013.

Is it really build 7955.. all the folders are from september 2010, and the installer is build 7600

"As with the previous build, this build is again on a private FTP but is expected to leak publicly in the same fashion as the previous build.

It almost feels like you're paraphrasing the first sentence in the second one except with a specification as to when it will be posted publicly.

you can; you just have to enable IO APIC on your System settings in Virtualbox (before running setup) and it will install. Of course, you can't install the GuestAdditions. I tried.

7955 requires hardware virtualisation support. Intel has a list of VT-capable processors - http://ark.intel.com/VTList.aspx

yeah, got that too, but not working shame

well, i just read it can't be installed on virtual machines... will give it a go on a new partition, see if it's working

Have you tried compatibility mode on the guest editions? That's how I got them installed on older Windows betas.

I've downloaded the ISO from the torrent and attempted to run it in a VMware virtual machine on
my dual-core machine. After the first reboot during setup, it falls over with the new style STOP
error at the "Starting Windows" bootscreen ... the error code is 0x0000005C . . .

Exactly the same here.

the leaked image is with 7850 installer + the fact it is x86


And you know this how? I know it's 32Bit. I am asking about the installer.

the torrent uploader said that himself ?!

Again. Hoe do you know this supposed fact? Do you have the proof other than your statement?

It's true, and it's already been explained to you.

Ci7 said,

Hmm, The torrent uploader isn't the original uploader. Also 7850 didn't use a W8 installer, it used the 7600 installer from Windows 7.

dude i am saying 7950 is homebrewed with 7850 installer

and yes it is not the same uploader

The creators and original denizens of Neowin didn't think so. Who are you again?

ThePitt said,

Betas are usually pretty good (as long as the machine isn't your main).

Totally agree with that, the one who say different is just a stupid or a child with a lot of time.

Nothing much more than a offical copy of windows 7 enterprise but what I hope to see RC is finished branding. Most of the UI complete in metro, because are is well old. More intergrated features, which means less drivers and more productivity, and an app store. but M2 looks good in progress

7850 was an Enterprise-based leak; 7955 is an Ultimate-based leak. Lots of similarities (in the case of 7, which both started from); however, even 7's Enterprise and Ultimate x32 SKUs have differences. (Ultimate has still been referenced, even within Microsoft, as the "kitchen-sink" SKU for any product line that uses it.)

Not interested yet. My Win7 box is running perfectly fine and for the foreseeable future I wont be upgrading...

But doesn't hurt to run Win8 in a VM to check it out

zombieChan said,

No; it doesn't. I have 7850 on a VM, and 7955 will be in another VM in about two hours.

One major change between the 7850 leak and 7955 - while 7850 was an Enterprise x32 build, 7955 is an Ultimate x32 build (there will almost certainly be some features unique to Ultimate in 8, as was the case with 7).

Stupid question: why can't Microsoft use an automated tagging of some type to tag each copy distributed internally so they can track a leak?

Supposedly Microsoft have been tracking the leaked builds and been firing the employees responsible.

They might, but that assumes that whomever is leaking these also knows how to remove those identifiers. With a company full of software devs with access to the source, somebody probably does know how

That hexadecimal string at the end of the build tag - that's probably it. Whoever started the leak of this image is a fool.

MS has been tagging builds since windows xp... they know who internally leaked it, people in the past during Longhorn beta where fired

Still waiting for an M3 build. So far I feel as if Microsoft is really heading in the right direction. Just glancing at the features of Windows 8 so far, I don't think i've ever been as happy with an OS as I am right now. I mean it's gonna have the feel of a mac (in terms of how easy it can be used) and the power of Windows. Wow.
I hope that made sense!

the feel of mac is probably on what they call the superbar with previously a title bar replace it into icon just like mac 8-9 years ago when Mac OS X was introduced..that's the part when the feel came from mac ! can you point out other else??

Well what I really meant and I guess wasn't the clearest on, is that it's becoming much more easier for the average user to pick up Windows and start using it. If you look at some of the features they're thinking of adding such as the Ribbon UI interface and the Webcam/Immersive Browser idea's, they're really catering to everyone now. Before for example, for my friends who always had trouble using Windows I would tell them that in my honest opinion it would be better for them to purchase a Mac that way they could just pick it up, use it for school etc without having any troubles. Now with Windows 8, I feel they could have a much better experience with Windows as it's bringing many "easy for the average user" with no bloat while still keeping the OS smooth, stable, and secure.

I thought "slate" 8 was supposed to be around late 2011. Will be interesting to see how this pans out if 2013 is the official deadline

blahism said,

2013 is not a dead line, it's a general release date. It'll probably RTM around August/September and released to Technet, MSDN, Enterprise customers in October/November with a release in January at CES or, Microsoft might push for it before December so OEM companies can cash in on new computers with the new Windows 8.

This is what happened with Windows 7. It RTM'd months before the general public release, not to mention we'll have tons of RC builds which can be turned into RTM at any given time.

Also, I can see major changes happening between now and early next year, then we'll see leaks where the UI will be adjusted and bugfixes implemented. With Windows 7, by Feburary (the year Windows 7 was released), we knew what the final product was going to look like, but people were still expecting Microsoft to pull an 'XP' by releasing a new UI at the very end, like they expected it with Vista. It never happened and don't expect it to happen this time. Microsoft have a timeline and they need to get it 'feature complete' so they can hammer the bug's.

Hope this helps, and while it is a little speculation, it's a logical guess.

Ugh, it's 32 bit


With such an early build, does it really matter so much that it's only 32bit? A 64bit build would
certainly be good to have if it were available. If Microsoft weren't so lax in trying to prevent
these leaks, rather than just a dire sounding legal warning emblazoned onto the desktop,
there probably wouldn't even be a 32bit build out there, let alone 64bit . . .


Maybe the next leak might offer something for users of both types of CPU.

There is said to be a 64bit still floating around on the private ftp but just hasn't been picked up yet. I just hate how they seed seed x86 version first. They did the same thing for Windows 7 builds a couple of years ago.

Soulsiphon said,
Got it, but thanks for the heads up.

Love the sarcasm. I am being serious, I really like it. I cannot convey this message without sounding sarcastic, but there is no doubt in my mind that what you said was really funny.

Why can't MS just put this stuff out for people to test.

"Here, torrent for build XXXX for Windows 8 pre-alpha build hooplaadooplaa, happy testing."

All this "magically leaked!!!1111" stuff is getting pretty tedious.

They typically do public beta/RC releases when it gets closer to being usable. The "average" user isn't really going to care about a pre-alpha unstable-as-hell build minus those of us who just want to mess with it in a VM. Plus things can still dramatically change in the OS, want to get things a bit more finalized.

They tried that sort-of during Longhorn/Vista. When they slashed features early in the timeline that were already announced, they received very bad PR. When Sinofsky started overseeing Windows Development (after Jim Allchin left), the focus was to remain quiet until beta therefore avoiding most of the bad pr when features are removed early in development.

Doing it this way protects them from liability

Because it's faster... FTP sends it out first and then people can up it. If it originated in a torrent everyone would jump on it and it'd be slow as hell. FTP is quite fast from BA. I hope more leaks go on there.

It's only faster while the bandwidth is available. If a ton of people hammer the server at once, that speed goes into the toilet.

Wrong.
FTP cumulative distribution speed is limited to the server bandwidth. The more people use it the slower is the speed.
With Bittorrent the cumulative distribution speed is unlimited and anly grows with the number of users.

However, the best way to get a torrent seeded is for multiple people to have it 100% as soon as it is released. That means that the bits have to get out some other way first (FTP, usenet, etc.). Too bad most people these days are too ignorant to use usenet, as it wipes the floor with torrents as a means to distribute large files to huge numbers of people. Once a single poster uploads it to their server, it can be downloaded by any number of people at their full connection speed.

but Bittorrent allow to use a algorythm of first seeder :
A torrent file is divided in several parts, let's say that it consist in 5 parts:
The seeder (alone) distribute the first part for the first peer, then the second part to the second peer... and finally the fifth part for the fifth peer and that's it, it is enough to the peer to complete the task to distribute the rest of the part and finish it without a seeder.
The problem is when a peer is not sharing but the odds and the system prioritize good sharer over the rest.

A growing number of internet service providers no longer support access to newsgroups,
so the only way the customers of those ISPs can get access to Usenet is through one of
the subscription based third party Usenet services such as UseNext and NewzBin.


So it's NOT about ignorance to Usenet at all, it's the increasing lack of accessibility.

DJGM said,

Yes, but that lack of accessibility started happening (due to lack of interest from ISP subscribers) AFTER people started migrating away from usenet to torrents and other types of p2p sites. Until the last few years, usenet was much too complicated for the average internet user to figure out, so only experienced computer users typically understood how to use it. The irony is that now the software is almost idiot-proof, but fewer people use it because it still has that "geek" and "complicated" stigma attached to it (along with the fact that fewer ISPs carry a usenet server anymore).

And it has almost always been the case that the best way to access usenet was through a third-party server, even back when EVERY ISP carried them. Nothing much has changed there, other than the insane level of retention that most commercial servers carry these days (500+ days isn't at all uncommon).

I'm well aware of how torrents (and usenet) work. The simple fact of the matter is that it is nearly always faster to initially upload something to usenet than even putting it out on a private torrent. Once a torrent is well seeded, then yes, it can approach the speeds (for downloaders) of a usenet download. But with usenet, the poster doesn't have to worry about people continually seeding it after it is posted. Once it is out there, it is essentially there forever (or until the retention of the longest running server runs out).

Newzbin does not provide newsfeed subscription services; it just indexes usenet postings.

+1 Newzbin is the equivalant of torrentz.com in regards to torrents. Service providers are people like Usenext, Giganews (who I use), Astraweb etc. Personally, I think Usenet is the best place to leak stuff. The reason being is that as soon as it's uploaded, it's mirrored to other servers and providers and those providers can handle the bandwidth.

The thing torrents suffer from is leechers, poor upload speeds from people with bad connections and traffic shaping (Usenet can be traffic shaped, but it mostly isn't).

Nothing much has changed there, other than the insane level of retention that most commercial servers carry these days (500+ days isn't at all uncommon).

That *insane* level of retention was because the then (and still) leader in third-party ISP Usenet servers in North America (Giganews) went to first the one-year retention, then the fifteen-month retention. (Now they have eighteen months of retention.) Back before Comcast dropped Usenet altogether, Giganews provided Usenet servers for Comcast. However, Usenet (as opposed to P2P and FTP) was the reason I kept blowing through even Comcast's soft caps. Most ISPs in North America (wireless especially) have harder (and lower) caps than even Comcast, which still gets grief for a soft cap.

Driver changes from Windows 7 - none. (Any hardware that Windows 7 supports, 7850 and later supports.)
Application support - except for applications that look for specific OS-isms, is identical to Windows 7. (While MSE doesn't work, ESET/NOD32 does, as does Avast 6.)
Browser support - the change here is IE (it is different from RTW IE9, and is not updatable to it); however, alternative browsers, including Firefox and Chrome, work just fine.

In order to get MSE to work simply right click, troubleshoot compaitbility.... select that it ran on a previous version (win 7) and u shud be good
