What SIW is
SIW is a Windows system information tool that analyzes computer hardware and software. It covers software, hardware, network, and system details, including licenses, devices, processes, services, network connections, and open ports. Reports can be produced in HTML, JSON, CSV, TXT, XML, or ODBC formats for saving or printing. Command-line options can select report modules, create, compress, or append reports, and run report creation silently. Reports can also be saved to a database with ODBC, emailed through SMTP, or uploaded through FTP, FTPS, or HTTP POST. The Technician's Version runs without installation from a USB flash drive, network drive, or domain login script. Its customization options include company logos, tailored reports, command-line-only builds, and builds without Passwords or Network modules; customization costs $50 extra. SIW offers a free viewer and a 14-day trial. Trial use is limited to specified 64-bit Windows versions, and some values are randomly replaced with ***TRIAL***. Paid choices include one-time licenses and annual updates.
