8GadgetPack - Gadgets for Windows 8 / 8.1 / 10 works fine with WIn10.
Let say 10240 is the release version that coming out on the 29th. Wouldn't that mean non-insider would start seeing windows 10 install prompt on the 29th or are they going to have to wait days or weeks before it installs or even downloads? After my testing (see my post in another thread) I suspect 10240 is actually a release version but can't say for sure.
They moved the release date for the Windows 10 OEM DVDs to the 31st. Perhaps that would be an indicator of when they plan on starting the non-Insider releases.
