System Information Viewer
System Information Viewer (SIV) is a Windows utility for viewing information about Windows, networked computers, and hardware.
What System Information Viewer is
System Information Viewer (SIV) is a Windows utility for viewing information about Windows, networked computers, and hardware. It reports CPU, PCI, PCMCIA, USB, SMBus, SPD, ACPI, machine, and sensor details, as well as firmware information. SIV can control supported all-in-one devices, though the maker advises reading its control guide first. The utility is available in a portable version and includes a command-line interface. Downloads are provided for 32-bit and 64-bit Windows, with separate options for Itanium, Alpha, and PowerPC systems. Listed operating systems range from Windows 11 back through older Windows Server and legacy Windows releases. Home use is free; commercial-use pricing is available by contacting the maker. Version 5.87 is listed as the current release, dated 14 May 2026. The support forum handles help, issue reports, and feature requests, with email available for some issues. Some motherboard utilities should not run concurrently with SIV because they do not use SMBus locks.
