Most of the Windows 10 builds published in the Insider program don’t come with ISO disk images, so the Windows 10 installer doesn’t get a ton of scrutiny. Every now and then, however, ISOs are published (in theory every time there’s a build pushed to the slow channel) allowing for fresh installs. Twitter user Tero Alhonen has spotted a new installation option in the latest ISO: Windows 10 Enterprise for Remote Sessions.
Some kind of remote desktop capability has been a part of Windows since Windows 2000 (and before that with third-party extensions), but Microsoft has always restricted it in various ways. Windows Server supports a single remote session for remote administration, or with suitable licensing, multiple remote sessions to provide desktops (or individual applications) for thin clients and remote workers. Desktop Windows (Pro or better) supports only a single remote session. Connecting to it locks the screen of the physical console, preventing multiple simultaneous users.
