Click a program shortcut. The app launches immediately. Use shortcut keys and it takes four seconds. e.g. - Click the Quicken shortcut: immediate launch. Use the keyboard keys specified for that SC <alt|ctrl|Q>: program opens in four seconds. Why? This did not occur in Windows 7, 8 or 8.1, to my recollection. If shortcuts are deleted and reconfigured, the keyboard accelerators may work as they should - until a reboot or two. Then it's back to lagging. START UP has relatively few programs. Both Program and Background settings for performance have been tested. See the attached for task manager details.
