Hello there, @SB70.

Currently, we have an ongoing investigation in which customers are unable to use the Product Help window. Our engineers are working diligently to get this fixed as soon as possible.

In the meantime, let's perform the workaround shared by engineers to get the Help menu function again. Let's delete the QBW.ini file in the C: drive on your computer. Let me guide you how:

1. Close your QuickBooks Desktop.
2. Locate C:\ProgramData\Intuit\QuickBooks[Version on your computer.
3. Delete QBW.ini.
4. In the Reset Internet Explorer Settings window, tick the Delete personal settings box.
5. Then, click Reset.

Once done, I suggest contacting our Customer Support Team so they can add your account to the list of affected users. This way, you'll receive an email regarding the issue once updates become available. Just provide this investigation number for easy tracking INV-28285.

Here's how:

1. Select QuickBooks Desktop Help.
2. In the Have a Question window, click Contact us at the bottom portion of the screen.
3. Click Search for something else.
4. Type in a keyword about your concern.
5. Hit Search.
6. Click on Start a Message.

Please check out our support hours and contact us at a time convenient to you. 

You can always visit this website: QuickBooks Desktop. Then, click + More topics at the bottom of the page. This lets you see all the topics on how to efficiently manage your income, expenses, inventory, and your desktop company file.

I appreciate your patience while we're working to fix this. You can always get back to us whenever you have other concerns. Take care!
