TaskSwitchXP is an advanced task management utility that picks up where the standard Windows Alt+Tab switcher leaves off. It provides the same functionality, and adds visual styles to the dialog and also enhances it by displaying thumbnail preview of the application that will be switched to. TaskSwitchXP also has a powerful process and window management capability that allows you quickly to close/minimize applications and their groups. The unique capabilities of TaskSwitchXP make it useful for tracking down multitudinous windows, and provide insight into the way Windows and applications work.
I miss this program in Windows 2000 sorely! Please point me to anything similar for Windows 2000 incase anyone comes across one. This is one which basically redefines Alt-Tab use. Once used to it, its impossible to be without it!
