only Windows 10 build 10074 ISO available download at Microsoft

After I download from one site

http://getintopc.com/softwares/operating-systems/windows-10-build-10122-iso-32-64-bit-free-download/

and realize it is only build 100064

and it wasted me 4 hours to do so

I think the following explain why

go to PC Settings > Update and Recover > Preview Builds > if there is a new build, it will show there and you can then click the Install Now button.

Hi Student,

There is no Windows 10 build 10108 available for public download currently, the available version to download for Customers by now is Windows 10 build 10074 ISO:

Professional:

Enterprise:

Besides, you may take a look at the Windows Blog, once new builds available, Microsoft would publish blog for the new build.

to download Windows 10 build 10074 ISO:

http://care.dlservice.microsoft.com/dl/download/0/B/7/0B78E5A3-FD98-4043-AB91-74D70F156873/10074.0.150424-1350.FBL_IMPRESSIVE_CLIENTENTERPRISE_VOL_X64FRE_EN-US.ISO

now the download is so much faster at 1.5-3.0Mb/s

average or mode is 2.7 Mbps

so download complete in 20 min as promised

now to right click on the iso files and burn the DVD

that may take another 20 min

So keeping this DVD just in case to roll back 

Windows 10 build 10074 Enterprise

Then I realized this maybe the one that caused the problem

Build 10130 just release 29 May and 

http://blogs.windows.com/bloggingwindows/2015/05/29/announcing-windows-10-insider-preview-build-10130-for-pcs/

We won't be pushing Build 10122 to the Slow ring due to a bug impacting upgrades from Windows 7 and Windows 8.1. Since the Slow ring build is what new people joining the Windows Insider Program for the first time will get, this unfortunately blocks us from choosing this build for Slow. If Build 10130 looks good in the Fast ring, we will look at pushing it to the Slow ring and releasing ISOs.

Summary:

The only official download from MS

is build 10074

https://www.microsoft.com/en-us/evalcenter/evaluate-windows-enterprise-insider-preview

at this moment by end of May

build 10122 is still unstable

so looking forward for build 10130 or there is no intermediate

last Chance will be in October 2015
