I read that Microsoft had released build 10525 to insiders on august 18th.
I went to Windows Update settings and enabled preview builds, set my ring to "Fast".
My MS Account is registered in the Insider Program and has been verified, the OS is activated.
Also the registry settings at "HKLM\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" are all correct, pulling builds from th2_release.
Is there any problem or i just have to wait?
Update: According to this post at Microsoft's community forums, the new builds can take up to 48 hours to become available.
