When launching Photoshop, Option-Command (Mac) / Alt-Control (Win) + Shift prompts you to delete the Adobe Photoshop settings file (which stores your preferences). Note: there is a very short window between clicking the PS icon to launch it and needing to hold down the keyboard shortcut, so get your fingers ready ahead of time!

To improve batch processing performance, in the History panel,select History Options from the fly-out menu and deselect Automatically Create First Snapshot. Depending on the length of your action, you might also want to reduce the number History States in the Preferences > Performance panel. Just don't forget to increase the number of states when you finished batch processing!
