The main features of Windows 7:
DirectAccess — Provides mobile users with reliable access to corporate networks from the Internet without the need to create a connection to a virtual private network (VPN).
BitLocker and BitLocker To Go - helps to protect data on computers and removable drives, if necessary, enforces encryption and creates backup copies of keys for data recovery.
BranchCache - reduces the time users from branch offices spend on downloading files over the network.
Enterprise Search Scopes - provides a single, simple interface for finding information on the corporate network, including SharePoint sites.
AppLocker - allows the administrator to determine which applications can and which cannot be run on user PCs using centrally managed but flexible group policies.
Improvements in virtual desktop deployment infrastructure Virtual Desktop Infrastructure (VDI) - Updated VDI interface includes support for multiple monitors and microphones. It also provides the ability to use virtual machine images for booting physical PCs.
Subsystem for UNIX-Based Applications (SUA) - a subsystem for Unix-based applications facilitates integration between Windows and UNIX / Linux environments.
Multilingual user interface (MUI) - the ability to create a single image for any language versions and any type of hardware (desktop, laptop, Tablet PC), which will provide a more convenient and fast deployment of the operating system. And later, users can, if necessary, switch the operating system interface (in particular menus, dialog boxes, training and support files) to any of the supported languages.

Activation is provided separately, which allows you to activate the OS with a legal key.
The assembly is provided in two versions: with install.esd and with install.wim (the image from which Windows is deployed during installation). Using install.esd can significantly reduce the size of the image. install.wim is used in the original version of Windows (that is, the version from the developers). The gradual transition to install.esd is caused by an increase in the volume of updates that need to be integrated into the assembly, as a result, in the current Windows 7 x64 build, the install.wim file exceeds 4 GB and the build image exceeds 4.38 GB, which does not allow writing it DVD5. Thus, you have two options for assembly. Choose the one that you prefer, otherwise they are exactly the same.
