Windows 8.1 final internal testing date is August 23rd, RTM to follow

We all know that Microsoft is preparing to sign off on the code for Windows 8.1 and ship it off to OEMs, this is nothing new, but we suspect that if you follow all the leaks closely, you will be curious when the platform will hit RTM. While we don’t have an exact date, we do have another milestone that will help paint the picture.

According to our sources, Microsoft has pegged August 23rd as the final test date for the Windows 8.1 codebase, meaning, we will likely not see the RTM sign-off occur before this date and it will likely follow the testing close window.

Now, this may seem a bit obvious as Microsoft typically waits until the last possible moment of the given time-window to sign off on the code but we had been hearing rumors that this upcoming Tuesday would be the RTM sign-off day.

Additionally, we are also hearing a similar report to Mary Jo Foley who said that RTM bits would not be available to developers directly after sign-off. While our source could not 100% confirm when the bits would become available, they stated that they did not see a planned released date for MSDN/Technet subscribers.

With that being said, RTM seems to be a bit more of a pomp and circumstance if Microsoft truly does not make the platform available to developers closely following RTM as it is expected that they will continue to tweak the code post RTM before it arrives in consumer hands.  Additionally, current indications suggest that we could see Windows 8.1 arrive sometime in October to follow Microsoft’s yearly cadence.

Windows 8.1 will bring quite a few new features to the table including the return of the Start button, enhancements to the Modern interface, and a bunch more. Steve Ballmer has referred to Windows 8.1 as a refined blend when making the comparisons of Windows 8.1 to coffee.

Windows 8.1 coming October 18th, Windows Store gets it a day early

I still don't believe the "MSDN subs will get it the same day as everyone else". The whole point of having an MSDN sub is to get the software to make sure your software is ready for it when it releases. How is everyone supposed to make sure their apps work just fine on 8.1 when you don't give them the RTM version early to test on?

It seems weird they are going to do this. I'm developing apps for Windows 8 and having the RTM before it hits the Windows Store would help me test my apps on it before submitting them.

its funny, because so many bugs found in w7 are still in 8.1 preview, which is one of the funniest if not sad things ever.

Like? (just curious)

I really hope they release it on Technet/MSDN before GA. Especially with Technet going away, you would think they'd at least put this out there before subscriptions expire.

agreed, it would be good to be able to do some testing etc.. on the final RTM before general release. Helps us IT folk keep one step ahead of the General Public/Consumers.

They really should not make Windows RT users wait until October for the update. If they want to clear Surface inventory then keeping those devices stuck with 8.0 until October 18th is a very dumb decision.
