CW-Sysinfo is a free, portable app to retrieve all your hardware and software information.
Some of the categories include:
BIOS, CPU, Motherboard, On Board Devices, Memory
Graphics card, monitor, resolution
Operating System, DMI, Hotfixes, Patches, Product Key, Live ID
Software, services, drivers, processes
Network, dial-up, user accounts
Hard disk, partitions
Microsoft System Tasks
and more ...
Once completed, you can optionally save your results as a text file or view it in ASCII. Optionally, you can select what information is saved.
We have tested CW-Sysinfo a few times before deciding to add it. One reason was that it opened a webpage on close with advertisements, but that wasn't a deal breaker. The other is that the language isn't completely English but has many words in German. At the end of the day, CW-Sysinfo is still simple enough to navigate and retrieves all the info you want and more.
