Close Quickbooks

End task on qbupdate.exe

Open this folder

C:\Program Files\Intuit\QuickBooks Enterprise Solutions 24.0\Components\Services\Images

Make a folder and call it DH

(I did this because it is related to Discovery Hub)

Move all pictures with the following names into that folder

Open Quickbooks

Voila

It may not stop the Discovery Hub Fully but at least I don't have to look at it anymore

Put the files back if it breaks anything

Don't delete the files just in case
