I am stumped. Every time I download a PDF or copy a PDF from an email attachment to my computer, I get a notification to open the PDF in Adobe at the bottom right-hand corner of my screen. Every time I check the box that says "Don't show this message again" and click the "x" to close the notification. And every time it opens the Microsoft Store so I can download Adobe Reader.

• I do not have any Adobe product installed
• There is no Adobe folder in Program Files, Program Files (x86), or Windows directories
• There is no Adobe folder in Users... AppData
• All notifications have been turned off in Windows, the Windows Store, in Edge, and in Chrome
• All registry entries pertaining to Adobe have been deleted

Yet, I still get the notification. What is the notification and how can I get rid of it with extreme prejudice?
