I can see how useful for you to remove the special offers block in QuickBooks Desktop (QBDT), @gerdgoebel.

Currently, getting rid of the special offers block or the advertisement section in the navigation bar isn't an option. It's there to guide and suggest how you can optimize your experience with the program.

In the meantime, I'd recommend visiting our blog to keep you updated with the latest news and feature upgrades in QBDT: The QuickBooks Blog. It also includes the link to the Quick Start Guide and QuickBooks Resource Center pages to further guide you in managing the growth of your business.
