"Don't show this message again" clicked in error - How To Reverse

I got you covered, @broadcaster.

Just a few thick and your QuickBooks screen will be back to its original size. Let me show you how in your QuickBooks Desktop (QBDT) software:

1. Go to the Edit menu 
2. Select Preferences.
3. Click Desktop View from the list and then the My Preferences tab.
4. In the View section, select the One Window option. 
5. Then select OK.
6. Close and reopen QuickBooks and your company file.

Thanks but let me rephrase the issue. When I change my screen resolution while Quickbooks is open, I get a Quickbooks Icon Bar message detecting a resolution change and asking me if I wish to use the side icon bar. It gives me a Yes or No option, and also, I can select Do not display this message in the future. See attached screenshot.

I clicked on Yes by mistake instead of No and selected Do not display this message in the future. Now, every time I change my screen resolution it automatically goes to the side bar. I don't want this. I had intended to click on No. How can I undo this permanent setting?

Thanks in advance.

I found an answer - Go to Preferences>General and select Bring back all one-time messages. That solved it.

Take care.
