Creating folders
The folder creation bug from build 4074 is still present in this build. You can apply a registry key by the following:

Installation
As typical of builds in this build range, it tends to take a long time to install and can be unstable.

No mouse driver in WinPE
On some computers and virtualizers, the WinPE doesn't support the mouse, so you must use the keyboard to navigate the WinPE. This seems to be related to using a PS/2 mouse, as USB mice seems to work fine for the setup.

DirectX
Although the Desktop Window Manager is present and can be activated by pressing Ctrl + Shift + F9 as in Windows Server 2008 build 4066, it will black screen due to a broken DirectX installation. It can fixed via the instructions listed on the Windows Aero page.
