July 15th. I think so. If I remember correctly, we had the first 10240 build exactly the same date last year.
Interesting. Well, if it is the RT-MDL of RS1 then at least I can do a clean install. Upgrading windows RS1 builds always breaks steam big picture for me.
Yes, everyone can stay "Insider" and upgrade their currently running OS each time, when a new Windows 10 Build is available, but there are many "Insiders", who just want to get their hands onto the RTM Build of the announced "Anniversary Update" before it will be released to the public.
