Excellent. thanks

By using DaRT, you can recover end-user computers that have become unusable, diagnose probable causes of issues, and quickly repair unbootable or locked-out computers.

When it is necessary, you can also quickly restore important lost files and detect and remove malware, even when the computer is not online.

DaRT is an important part of the Microsoft Desktop Optimization Pack (MDOP), a dynamic solution available to Software Assurance customers that helps reduce software installation costs, enables delivery of applications as services, and helps manage and control enterprise desktop environments.

This comes in a bootable ISO format, so simply burn it to disc or create bootable USB Flash drive and you're good to go. You can then boot Into any Windows 7 edition in the 64 bit architecture (and Windows Server 2008 R2) and perform tasks on the OS thereafter.
