i do belive wzor is right, oem-partners to get RTM in july/august, GA retail date september-october? But if you are insider you will get to upgrade your build in july to rtm, while the ones who arent insiders must wait for ga-date or leak .iso
Last build in impressive branch is 10120, so...like previous bet, new insiders preview build will go from 1013x to 1015x (if this will be released from half to end june)
Looks like a fake. What on earth is "Microsoft Pre-Release Product Codenamed Cloud" ? It also has the old .exe icon, you can see it if you look at the taskbar carefully. Start menu is a complete fake or a 3rd party start menu alternative, Win10 doesn't have a menu like that. And, last but not least, glass thingy on titlebars must be Glass10 or something else.
Go to , run , regedit then : look for : [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion] change "CurrentBuildNumber"="10120" to any ****
