Speccy is a handy, portable system information tool from the makers of CCleaner
Speccy is a more recent addition to the family, and it's a handy little tool for gathering information about the hardware in a Windows PC. While it's not as detailed as some other system information tools, Speccy still provides a good deal of essential information and gathers it quickly. You can also take a snapshot of the system details and open them for review later.
As with other Piriform apps, Speccy is available either as an installer or a zip-compressed portable app -- perfect for taking with you on your USB flash drive.
