This build features a new background after installation.
Also the taskbar is no longer transparent, the new search box is enabled by default and the icons behave differently.
When minimizing, they only display a bar the bottom, with multiple windows open, it displays to different colors.

Settings has been updated with a new front page which houses the options in sort of tiles. When you click on them, they display the regular settings.
Some applications has been updated such as Alarms and Calculator. While others such as Camera and Store have a ''Beta'' variant installed besides them.

The new Store is buggy and slow, some pages will not load completly, but the music tab works fine.
It also includes an updated version of the new Touch Start Menu, although, it doesn't display any boxes or apps, but it can stretch over the whole screen.

Also found is the new Xbox App, which is not finished by far.

You will notice in the Control Panel that the Windows Update option is disabled since it is no longer present, but only in the new Settings application.
The Help & Support application now redirects to a website instead of opening the included help.

Cortana is also includes and functions as it should like on a Windows Phone, although you can see that it still early in the process.

It is also now possible to upgrade from the Technical Preview (running the Pro edition) directly to Enterprise.
Use the ''Add Windows features wizard'' and input the Technical Preview for Enterprise key.
