You can use QuickBooks for up to 30 days without registering the product. After that you must register to keep the software active. Registration is free and provides the owner of the software with update notifications and technical support. If you install the application on a new computer, or if you reformat the hard drive and reinstall QuickBooks, you must reregister the software. You can verify the registration status and launch the registration wizard from the Product Information window in QuickBooks. Warnings Writer Bio
