D7 provides a collection of PC tweaks and tools that can help you optimise your PC, repair problems, remove malware and more.
The program is portable, and the author's intention is that you'll combine it with many other free tools to build your own troubleshooting toolkit. Click the Malware tab, for instance, and you'll see buttons to launch programs like Malwarebytes and AutoRuns. However, you'll need to manually download these and copy them to D7's own folder before these will work.
D7 does include plenty of tools of its own, though. So there are options to carry out offline Registry editing, for instance. A "DataGrab" function allows you to collect the data you need from the current system. And there are modules to carry out CPU and RAM stress testing, a Tweaks section with various Windows tweaks, a set of Repair tools to, say, repair and reset the Windows firewall, and various other features.
