Chinese Windows 8 Release Preview (build 8400) leaked

Well, Microsoft is probably not particularly happy that this happened, but it appears as though the Chinese (ZH-CN), 64-bit version of the Windows 8 Release Preview has leaked just days before it is supposed to be officially released. The download comes in at 3.34 GB and most likely is only in Chinese, with an English version yet to make a leaked appearance.

While we haven't received proper confirmation that this is an actual Release Preview build and not a fake, Canouna mentioned on Twitter that the size seems to be legit. Other people in a related thread on the WinUnleaked forums have pulled apart a partially downloaded ISO and found an installer that appears to be for the legitimate Release Preview (build 6.2.8400). Apparently this guy over at PCBeta has already installed the build and can also confirm it is indeed a legitimate leak.

Image name:
8400.0.WINMAIN_WIN8RC.120518-1423_X64FRE_CLIENT_ZH-CN-HRC_CCSA_X64FRE_ZH-CN_DV5.ISO

MD5: F3AC28467258EC9F0ECEAF9690A0F06E
SHA1: C21B69413E08FCFB756EEDB2B99D0C0472486D1C
CRC32: 67F85067

While we obviously can't post direct links to it, if you follow one or two Windows 8 watchers (or head to the sources) you should be able to find out where it is being hosted, but that is of course if you're interested in playing around with the Chinese version... 

Update: Canouna has proclaimed that this build is "100% legit" after checking setup.exe and product.ini, pretty much confirming (along with other reports) that the ISO does indeed contain the ZH-CN version of the Windows 8 Release Preview.

Am I the only one who didn't get excited over this?

I have it installed and I`m still not excited about it, in-fact I was more excited about it before I installed it, and that was only about 3-4% excited out of a possible 9999% of excitement

I imagine any changes that are potentially "breaking" in any significant way will already have been completed by the time of the RP. Further changes will be limited to fixing such breakages and incorporating final changes that from an engineering perspective are highly unlikely to cause significant new faults.
Hopefully this version will be stable enough to use - I found Metro was still too unreliable in the CP with apps often dropping out to the Start screen on load or simply stalling at the splash screen.

The Release Preview will allow upgrading from the CP, right?

Canouna said in his forum that you can't. It will 'upgrade' the CP creating a Windows.OLD folder so you will have to install everything again.

Maybe he was talking about upgrading from English to Chinese version? I definitely can't see why upgrade shouldn't work for the same language installation

Microsoft don't want any bugs being past on.

if this is the RC.. why the fake Aero in setup?

MS is really lazy I swear (on the design side).

Zain, I respect your work, but I'm quite surprised you've even said this.

This is RC, but Microsoft have said all the last major work won't be released until the actual RTM. Microsoft are not lazy, they've just not managed to finish the setup files in time for RC.

source? if this is true than that's actually really good, but I thought Microsoft had already put in all the major changes to the RP

Adam Vester said,
A German ver has leaked also. And you can just go to windows update and select English language pack btw.

No you can't, language packs have not been released on WU for the RP build.

There was a link flying around for an English version download as well, but the link required login details. Not sure if someone has managed to get it.

Just to add on to what I Said, it seems like someone was trolling. Sorry to get anyones hopes up.

You should tell us who Canouna is in the first paragraph.

The own of site, winunleaked.tk, he is kind of tester of Windows 8 builds and has access to them earlier than any of us..

Well earlier then anyone on here who isn't in the TAP/OEM Connect program... Cause TAP/OEMs got access 3-4 days ago.

If my memory serves me right, Canouna is a major contributor to MDL Forums (and he's also registered on Neowin Forums who beta tests Windows for Microsoft. He also owns winunleaked.tk, but (I think I read him say this once ) he just posts screenshots since he "still respects them" and doesn't wanna leak too much or something. basically he leaks screenshots & info

Sorry to go off subject but has anyone heard of whether there will be a release preview on the new Windows Server?

I guess it would be some hours after win8 RP.(Pour English make me crazy)Just like server8 beta。PS:win8 RP will come out on 1st june。

Good thing is the Chinese version. If it had been the English or Spanish version...oh, I probably would have waited the few days left to download it from microsoft.com :-)

I just hope the download will be a quick as the Consumer Preview.

zerozzc said,

Just 3 days.

I should caution the both of you. The supposed launch is just 3 days away, and there has been no official word. We knew of the Consumer Preview a month before the launch in Spain.

No, just rumored. It's a week away and nothing.... Not looking too good. Should have been confirmed now via a press release or invite of some kinda.

They said the first week.

As far as I know, Microsoft has made no official comment, and it's already Tuesday of the "supposed" launch. Canouna is the only one I've seen make a comment on the first of June date.

I remember seeing a pic (on Neowin!) of the RP conference where they announced that the RP would be released first week of June. what do you mean "Tuesday of the supposed launch" ? it's not the first week of june yet

Well, rumor has it it's coming on June 1st. We're three days away from that and no announcement, so my money is that it's coming next week, around the 6th.

Would it be possible to install a language pack over this?

I don't think so because the relevant language packs are not available yet

Some people in PCBeta who downloaded failed to install, suspecting a tempered install.wim.

Chocolate tempering is as far as I am willing to go!! Windows tempering? That's a tough one!!

LOL, because the leaker has to remove the OEM ID.

I found a link to the Chinese leak and am currently downloading for VM-based install testing. (That is what I usually do with OS leaks - even if they are US English.) Since I also have the Consumer Preview (albeit in English), I can compare them side-by-side. In addition to being Chinese, the leak is x64 - not x32.

Happy 12kb/s.

Is it confirmed 1 Jun will be officially released? In 3 days?

I will install it on my back-up PC to keep playing with from time to time. It will be there until expiration, but it's not in my intentions to ever buy it. I'm fine with 7 and altlough my Graphics Card support Dx 11.1, there aren't real benefits as gamer.

it rumored to be first week of june http://www.engadget.com/2012/0...-coming-first-week-of-june/
Neowin reported june 1st

"1st week of June" was the official announcement.
"The 1st of June" is a rumor.

I'm inclined to believe it
