SysGauge, a system and performance monitoring utility, available as a portable app, is a nice utility that you may want to consider for the tech toolbox. Appears to support all versions of Windows, XP to Present… Windows Server versions also supported.
One notable feature of SysGauge that I was impressed with is the system analysis feature. Just press the ‘Analyze’ button located on the main toolbar and SysGauge will perform a quick system status analysis of your PC that will check the CPU usage, memory usage, the operating system status, the disk space usage for all disks and produce the results in a nice dialog summary.
SysGauge is a system and performance monitoring utility allowing one to monitor the CPU usage, memory usage, network transfer rate, operating system performance, the status and resource usage of running processes, file system performance, USB performance, disk space usage, disk read activity, disk write activity, disk read transfer rate, disk write transfer rate, disk read IOPS and disk write IOPS for individual logical disks or all physical disks installed in the computer.
