SIW (System Information for Windows) is a Windows diagnostic utility that reports details about a computer's hardware, installed software, network configuration, and system settings. The publisher continues to offer SIW, but the current product is a commercial tool with a free 14-day evaluation, not the same as the old freeware edition described in many archived portable-software listings.
SIW — System Information for Windows
What Information Does SIW Show?
SIW gathers system details that can help with troubleshooting, inventory, and technical support. Depending on edition and version, its reports cover hardware, BIOS, operating-system details, installed programs, devices, memory, storage, network settings, running processes, services, and other system properties. The publisher also describes monitoring and reporting features for technicians.
System-information utilities can display sensitive details such as software license identifiers, usernames, network information, and device configuration. Review reports before sharing them publicly or sending them to a support contact.

The current trial should not be confused with the older free personal-use editions found on software archives. The legacy SIW Portable package maintained through PortableApps.com is explicitly discontinued, and its archived notice warns that the old free edition does not work on Windows 8, 8.1, or 10. Do not use that old package as a substitute for the current release on a modern computer.
Is SIW Still Portable?
The publisher describes SIW as a standalone utility that does not require a conventional installation and offers a paid portable version. However, the old free PortableApps.com edition is discontinued. Check the current license and download details directly with the publisher before assuming a specific edition can be run from a USB drive.
Alternatives
If you need a free Windows diagnostic utility, Microsoft's Sysinternals system utilities provide focused tools for tasks such as examining startup entries, process activity, and system internals. For a broad hardware inventory, compare maintained utilities and confirm their current licensing and features before downloading.
Frequently Asked Questions
Is SIW still free?
The current publisher offers a free 14-day evaluation and sells licenses. The old free personal-use edition is separate from the current commercial product.
Can I use the old SIW Portable edition on Windows 11?
The old PortableApps.com package is discontinued, and its notice warns that the old free edition does not work on Windows 8, 8.1, or 10. Use the publisher's current product information instead of relying on that legacy build.
Can SIW reports contain private information?
Yes. System reports may include usernames, network configuration, software identifiers, or other details that should be reviewed before sharing.
Final Thoughts
SIW remains available from its publisher, but its current commercial release should not be confused with the older freeware edition once distributed as SIW Portable. Check the publisher's current trial, licensing, and compatibility information before downloading, particularly if you need to run the utility from removable storage.
