What device driver tool is used to replace a driver with one that worked before the current driver was installed?

The device driver tool used to replace a current driver with a previously functioning one is called "Device Manager" in Windows. Within Device Manager, you can right-click on the device, select "Properties," and then navigate to the "Driver" tab to find the "Roll Back Driver" option. This allows you to revert to the last installed driver, which can resolve issues caused by the current update.
