Vmware Player

Run virtual machines created by VMware Workstation, GSX Server or ESX Server. VMware Player also supports Microsoft virtual machines and Symantec LiveState Recovery disk formats. Easily and safely evaluate pre-built application environments, beta software, or other software that is distributed in virtual machines, without any installation or configuration hassles. Share a virtual machine with a colleague or friend. And Try this: "VMWare Player cannot create VMWare images like VMWare Workstation can. Fortunately, a utility called QEMU can."

Hard Drive Indicator

Displays a system tray load indicator for your local physical disks. Has a 5 bar resolution for both read and write operations. Has a small memory footprint and low CPU utilization. Auto-calibrates itself to ensure that the output is relative to the disk usage for the previous 60 seconds (Read and write scales are not relative).
