2. and 3. written guide:
Test 4: Latitude D820 (after Test 3) with a new SSD. Clean install using RDVM1 and no Microsoft Account. Microsoft Product Activation passed
Installation Conclusions:
• The Recovery Drive is Edition Locked but not System Locked or Microsoft Account Locked. It gives a vanilla Windows Clean Reinstallation. Product Activation allows small changes such as SSD/HDD/RAM changes.
• Windows Insiders who had Build 10130 or earlier will upgrade to 10166 and then to RTM 10240 when logged in with a Microsoft Account. Once they have registered there device as a Windows 10 RTM device they may leave the device from the Windows Insider program. They may then create the Recovery Drive and clean install (with or without a Microsoft Account) and have an activated clean install of Windows 10 RTM. This free upgrade does not require a base Windows 7 or Windows 8.1 license so those who joined from capable systems running Windows XP and Windows Vista systems will get the free upgrade as my guides hinted away back since January 2015.
