What is SIW?
SIW is an advanced System Information for Windows tool that gathers detailed information about your system properties and settings and displays it in an extremely comprehensible manner.
SIW can create a report file (HTML, JSON, CSV, TXT or XML), and you can run it in batch mode (for Computer Inventory, Hardware, Software and Network Information, Software License Management, Security Audit, Server Configuration Management).
The system information is divided into few major categories including: software, hardware, network, real-time monitoring and miscellaneous (including lost passwords).

Said about SIW as an alternative
helps find lost passwords
I can't really speak about some of the others, but I have used SIW in previous years. It was perfectly accurate and non-obtrusive.
