Windows 8.1 Pro RTM x64 has leaked

Windows 8.1 hit RTM only a few days ago and while Microsoft has been holding the final bits back from developers via its MSDN/Technet channels, the English version (note: the en-US 8.1 Pro x64 install.wim leaked) of the platform has now leaked. The English leak follows a series of RTM leaks that have occurred since the platform was sent to OEMs that appear to have originated from China.

Microsoft, for whatever reason they see fit, has decided against posting Windows 8.1 to its developer channels and wanted to make all users wait until October 18th before they can get their hands on the update. But, when there is a will, there is a way, and the Windows 8.1 community has been able go against Microsoft’s wishes by leaking a copy of Windows 8.1 that was sent to OEMs.

As with any leaked copy of any software, you will be installing the software at your own risk and since the bits come from unofficial channels, they could be modified without prior knowledge.

With that being said, the English version of Windows 8.1 is now floating around the web in all of the usual places (we won’t link to them per site policy) but if you fancy installing Windows 8.1 now, go forth and download.

For those of you wanting to wait until Microsoft releases the update officially, you will get your chance on October 18th at retail locations and on the 17th via the Windows Store.

[Update] It looks like the wim file might be corrupt, proceed with caution. The wim, which many reported as corrupted, can be fixed and will allow for a proper install.

>>It can be fixed, but it is still buggy as hell, there's a reason the wim was corrupt in the first place.

Well I'll wait 6 weeks rather than take my chances with Chinese hackers. Better safe than sorry, there's nothing in the RTM that is much different than the Preview.

other than just getting the final RTM installed, done and over with. I personally will not be using Windows 8 AT ALL until the RTM of 8.1 is out.

I wanted to install Windows 8. The only thing that has been holding me back is graphics card driver.
I experienced a lots of problems with my current Windows 7 install.

If his hardware has problems with Win7 drivers.. Win 8 drivers will be even worse... Seems pretty easy to understand to me..

What do windows 7 problems have to do with windows 8?

There are no Windows 8 driver released yet for my model. With Windows 8 (not 8.1) I can use Windows 7 driver no problem. So I did the same as in Windows 8.1 and crashed. Not sure if my hardware or it's from that news saying every computer's graphics card has been effected by Windows 8.1 and MS fixed it. (And I never tried install Windows 8.1 since)

Yep! I try to stay out of Windows 8.1 until a fully stable Windows 8 driver has been released for my model! I'm not risking it yet...

What model do you have? Because the official Win8.0 driver worked fine for my ancient 8800GT in 8.1 preview.. Haven't tried 8.1 RTM yet though...

Toshiba Satellite A660. I can use Windows 7 Graphics Driver on Windows 8, but Windows 8.1 Preview has crashed. And some website posted a news saying that it happened to all PC due to coding. But I haven't tried since...

I meant what graphics card model? There are many different Satellite A660's.. Most of them I saw had a geforce 330 or similar, but one had Intel HD graphics.

Yep it's a nvidia 330 gtx!

Then you should really get the Win8 and Win8.1 Preview drivers. They do exist for your model graphics card, I checked! There have been stable Win8 drivers for awhile and the 8.1 Preview drivers have been pretty solid as well. There is no reason to still be using Win7 drivers for it. They run great and haven't caused any crashes.

Ohk, Thanks dude. Some time you can't rely on manufacture's website for drivers, oh well!
Is this it, sorry:

Yep thats the Win8.1 drivers but they are still in beta. 320 i believe is the stable Win8 drivers. That will probably still work in win8.1 haven't actually tried..

Ohk. Thanks

The latest posts on MDL report that it will install, however it does not let you update from 8.0 and there are a few things that do not work (e.g. Net4 apps) and there are a number of errors. As many over at MDL I recommend waiting for a proper leak (Wzor). Finally, I suggest updating the update in the OP as people may assume it will work without issues, which is not the case.

I don't wanna do a few tweaks. I don't wanna mix and match. Finally I don't want a Frankenstein Build.

I'll wait for an untouched ISO....

Never understood the fascination why people can't wait till October 18th. They have to have it...now now now.

Good grief. You can't wait?

I don't get microsoft. It seems like they're getting dumber by the day. They missed the mobile devices wave, surface pro and RT are a major flop (which wasn't surprising) consequently they write off nearly $1 billion in losses . They botched the xbox one unveiling. Windows 8 was a mess, putting the start screen on desktops and servers and forcing us to use it. I didn't know whether to laugh or cry. All i could do was shake my head at their stupidity. They Kill Technet for no good reason, thus ****ing off the tech community. Now they hold back windows 8.1 from us. I probably missed a few other things but if they're trying to look like total jack-asses they're succeeding fabulously. I used to like microsoft but these days I avoid any product or service related to them and I also recommend alternative products at work, to friends and to anybody else that I talk to.

What would happen if this got installed on top of Enterprise? Or will it get some error that it's not the right version?

It likely WON'T install over Enterprise (SKU/version mismatch) as Enterprise SKUs won't install over non-Enterprise SKUs - it is also why the Pro/Core 8.1 Preview wouldn't upgrade Windows 8 Enterprise. However, the leaked 8.1 Enterprise (Chinese or mods thereof) likely WILL upgrade either 8 Enterprise or 8.1 Preview Enterprise SKUs - that is something I'll be testing in VMs later.

The install.wim is fixable, just need to do a few tweaks to it using the ADK (Windows Assesment and Deployment Kit)

So how can we fix it ?

I'm not surprised if Microsoft decides to put it on MSDN/TechNet in the upcoming week(s) and stating "do to popular demand and listening to our valued professionals we have decided to put the final bits for download on these platforms"

Mr. Dee said,
Sorry, I'm not that desperate. My MSDN Sub is alive and kicking, I can wait.

who cares about MSDN? you'll get it when everyone else does, even without that or technet, so...

This isn't the final 8.1 just because its RTM. Read the ms blog. I bet they changed to doing it this way to prevent leaks such as this outing all the features. Great idea.

freak180 said,
so foolish then explain why MS gave the same thing to OEMS??

because its enough for oems to bring up their systems with. the driver model and all that is complete in the RTM. alot of things are not. you can bet your bottom dollar that the architecture of the os was built for this. no longer do rtm builds leak all the features before ms wants to present them.

did you install the chinese version? i did. i didnt see alot of major differences(even though i tried my best with translating everything i could find).

freak180 said,

Microsoft in their wisdom have decided to alter the meaning of the term "RTM". Up until Windows 8.1, RTM meant released to manufacturing but now it means released to manufacturers. Software developers need to have a reality check, what's more important, ensuring Windows 8.1 runs optimally and stable on the diversity of 8.x compliant hardware, or that a developers application is 8.1 compatible?

Windows 8.1 is currently not complete but will be continually updated and optimised until the announced October 18th release date.

Can't wait for Microsoft to reveal all of the exciting features they're still working on for 8.1 ...

Same. Maybe they'll call this Windows 8.11

Not true. While there is no ISO, the en-US install.wim of 8.1 Pro x64 did indeed leak. If you know what you're doing, the install.wim is all you need.

Mistitled title of this news! Its just modlifilded chines version not original english iso!

modlifilded chines huh? lol

Emil Valsson said,
I'll stick to what works better, Windows 7.

So you've gotten your hands on the RTM of Windows 8.1 and have used it enough to legitimately claim that Windows 7 is still better? Awesome!

I don't care how gr8 are new features unless trusted benchmarks are posted. If performance against 8.0 is equal or grater, then OK.

Again guys, THERE ARE NO ISOs of the leak! It's the install.wim of the en-US 8.1 Pro x64 with full en-US language. Just wait a few hours guys and follow the threads on MDL.

One thing I wonder, is if Microsoft would be able to see that you logged into Windows 8.1 RTM with your Microsoft account? I mean, up to which extend is it illegal to use a leaked ISO with software that technically hasn't been released yet?

so all MSFT accomplished was keeping windows 8 out of developer hands while pirates and the press get to enjoy it.

kind of backfired huh? seriously, MSFT has had a stupid move and responsible parties should be getting a box to pick up their office stuff and an employment termination notice.

So we should feel confident that an obviously modified build by some Chinese dude is OK to use on our computers? Thanks but no thanks. If it was an unmodified ISO identical to what we'll see on MSDN, etc then OK but some Chinese modified version they can keep...

The en-US 8.1 Pro x64 install.wim leaked - no official ISOs yet... and there probably won't be for awhile. No doubt AIO ISOs of the 8.1 Core/Pro x64 RTM will appear within a day or so.

NICE!!

It was obvious this was going to happen! The idiots at MS should have just released it to testers at least if not the general public instead of unnecessarily holding on to it and pi***** off a lot of people.

"It appears to be a repacked version of the Chinese install with an English language pack"
It's the other way around apparently, it's an En-US version, but with a Chinese version added into the wim, you can choose between English(original) and Chinese (slipstreamed) during install.
(I can't verify this yet, but this is the info the leaker provided)

Given Windows is language-neutral, it doesn't matter if it's using a Chinese or English language pack. Yes, even English is a language pack since Vista.

Yes... Until Microsoft posts this to MSDN and we have a checksum for it to check against, I think it's pretty hard to say what's real or not, or whether something has been tampered with. Man, with the excitement now, this must be a perfect moment to try spread tampered releases.

Sure, there are digital signatures for executables, but I'd rather not personally go through all that, and those aren't fool-proof since plenty of modifications are possible besides in those files.

Classic, just like the PS3 jailbreak, take something away from people and they'll only try harder to get it (back).

Microsoft insists in ignore a key important factor: The will of customers. They should fire their entire corp marketing division and hire a goat instead.
