How do I uninstall and reinstall the HP All-in-One software on a Windows computer?

Go to Start > Control Panel > Add/Remove Programs, select HP Deskjet All-In-One Driver Software, and click Change/Remove, following the onscreen instructions. Disconnect the HP All-in-One from your computer and restart it before reinstalling. Then insert the HP All-in-One CD-ROM and run the Setup program, connecting the USB cable only when prompted. You can verify successful installation by checking that the HP Solution Center shows the Scan Picture and Scan Document icons. (Page 9)
