Nothing here yet.
Here is a tip from Gabe's blog.
We’ll be publishing the build later this afternoon and it should be available everywhere by end of day. If you’re actively downloading 10158 when 10159 is published, you may get an error 0x80246017. If that happens, just reboot your PC, go back to Settings and check again and you should see 10159 offered to you.
Windows 10 build 10159 available to download on the Fast Ring later today
Microsoft claims that build 10159 has passed all of the company’s internal criteria with flying colors after a week of testing. The new build includes over 300 fixes, so it’s a nice change.
One more BUILD.. One more BUILD!!!
