I'm currently using the ESD from a few days ago and Windows update says Im updated but mine ends with 10586.0 and it didn't install any updates to end in 10586.3
Media Creation Tool is 10586.0 It has less options than the 10240 version. Windows 10 or Windows 10N only no Home or Pro choices. Will have to see what install options are available. x86, x64 or both are still available choices.
First difference from Insider and This release is in the description of install.wim file: Insider: Name: Windows 10 Pro Technical Preview Description: Windows 10 Pro Technical Preview TH2 from WU: Name: Windows 10 Pro Description: Windows 10 Pro
Yes it is RTM like 10240 Build who is realeased in middle of Jully for Insiders and who is sended to manufacturers, so witf Update from last Tusday this build changed to 10586.3 and this build will be officially Realeased so u can install this build 10586.0 IT IS RTM.
