D7 is a tool for PC technicians to aid in many tasks and provide a uniform procedure for technicians to follow. It has many capabilities and many uses including offline and live malware removal assistance, offline registry editing, data backup and restore, CPU/RAM stress testing, information gathering and quality assurance uses, etc. etc. Too much to list here, right now at least. It also combines some other projects of mine such as DataGrab and CheckDisk, among other smaller things.
