Eraser is an advanced security tool (for Windows), which allows you to completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. The patterns used for overwriting are based on Peter Gutmann's paper "Secure Deletion of Data from Magnetic and Solid-State Memory" and they are selected to effectively remove magnetic remnants from the hard drive. Other methods include the one defined in the National Industrial Security Program Operating Manual of the US Department of Defence and overwriting with pseudorandom data. You can also define your own overwriting methods. Erase files and folders securely.

System Information Viewer is a general Windows utility for displaying lots of useful Windows, Network and hardware info - CPU info, PCI info, PCMCIA info, USB info, Machine Info, Hardware Sensors, Networked computers, Operating System Information and more. I use Craig Hart's pcidevs.txt file for my PCI device display with my usbdevs.txt being used for the USB devices, mondevs.txt for monitor descriptions and pcmdevs.txt for PCMCIA device descriptions. SIV is designed for Windows 10, 7, XP, Vista, 2008, 2003, 2000 and NT4. Windows 95, 98 and Me are also supported.
