The first registry value, [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\BackgroundAccessApplications\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy]
"Disabled"=dword:00000001
appears to be undocumented, but seems to block the automatic installation of software by Microsoft on a Windows 10 system.

The second registry value, [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager]
"SubscribedContent-338388Enabled"=dword:00000000, is for disabling "suggested" applications in the Windows 10 Start menu.

Also note that this workaround is for a single-user system, where the change is applied before the system has internet connectivity. For multi-user systems, this change must be applied to each user. Alternatively, it can be applied to the default windows user profile hive, and the change will be there for newly-created users.
