QuickBooks is configured to download updates automatically from the Intuit server. You can also update QuickBooks manually.
If you choose not to update QuickBooks automatically, you should update your copy of QuickBooks about once a month.
Note: You can't turn automatic updates off if you have a subscription plan such as QuickBooks Pro Plus or QuickBooks Premier Plus.
