What Navrátil Software System Information is

Navrátil Software System Information (NSSI) is a free Windows utility for viewing computer hardware and system details. It is described as useful for technicians, computer purchase or upgrade decisions, and driver searches. The maker says it can run without an operating system, fits on a system diskette and can also run from a USB flash disk. NSSI detects mainboard, CPU and cache, BIOS, video, memory, storage, network, sound and port information, as well as devices on PCI, PCI Express, PCI-X, AGP, PnP, EISA and PCMCIA buses. It reports OS and DOS details, loaded drivers and TSRs, and includes CPU and FPU benchmarks plus tools to check for CPU bugs. The product page states support for 48-bit LBA and disks up to 128 PB. Memory type and memory-slot details are available only with some chipsets. The listed version 0.60.47 is a recommended upgrade, released 2026-08-17; it removed a future-year date check and included small bug fixes and code optimizations. The listed price is free, with a 498 KB download. Navrátil Software began developing mainly non-profit DOS utilities in 1994; NSSI work started in 1996, with its first public release in 1997.
