About SIW
SIW (System Information for Windows) gathers details about a PC in one program. On the software side it lists the operating system, installed programs, software licences and product keys, running processes, loaded DLLs, drivers, services, autorun entries, scheduled tasks, codecs and certificates. It also reports hardware components and network configuration.
It suits technicians and people auditing a machine who would otherwise use several separate tools. It is updated often; version 16.15 came out in September 2026.
