How to install Windows 10 Anniversary Update on Windows 10 Enterprise edition

Solution 1:

To Upgrade the Windows 10 Enterprise Editions, get the 1607 ISO from MSDN/Volume Licensing portal, mount the ISO via double click on it, run the setup.exe on the virtual DVD drive, now select Upgrade

and next select Keep personal files and apps

This upgrades Windows 10 to the Version 1607 and keeps all installed Windows Applications.

Solution 2:

I found a solution that actually works for Windows 10 Enterprise. Takes some tweaking and it will install Build 1607. Make sure you have a backup. Secondly make sure you are signed in with your Microsoft Account. Then follow these steps below.

1. Open regedit.exe and navigate to HKLM\Software\Microsoft\Windows NT\CurrentVersion
2. Change ProductName to Windows 10 Professional
3. Change EditionID to Professional
4. Navigate now to HKLM\Software\Wow6432Node\Microsoft\Wind­ows NT\CurrentVersion
5. Change ProductName to Windows 10 Professional
6. Change EditionID to Professional
7. Close regedit.exe (no need to restart)
8. Start the Windows 10 Pro installation from your installation media. (Download the Media Creation tool from Microsoft - http://go.microsoft.com/fwlink/?LinkId=691209 or https://www.microsoft.com/en-gb/software-download/windows10 and click on the Download Tool now)
9. Do the upgrade, will download and install, keep all files & settings.
10. Will reboot several times, once finished, log back in with your Microsoft Account and it will automatically link your enterprise key to the install and you will be back on Enterprise Edition and have Build 1607 installed.

I did it on 4 machines today and it worked every time.
