OneNote Uninstall Problems

I've been trying to remove OneNote from my computer.
Previously, I used "Method 2" from
How to Stop Microsoft OneNote from Starting Automatically on Windows | Plexaweb
Yesterday, I used Used Revo Uninstaller Pro to uninstall "...\Windows\Start Menu\Programs\Startup\Send to OneNote.lnk"
Somehow my MS Office programs were uninstalled.
I reinstalled MS Office.
Now I have a weird folder on my desktop: "Microsoft OneNote Namespace Extension for Windows Desktop Search." This folder only has 3 context menu options: Cut, Create Shortcut, and Delete. One can't view its properties.

This folder does not show up when viewing my Desktop using File Explorer.
Before the MS Office reinstall, I had a blank icon on my desktop. I deleted it because I couldn't view it.
My goal is to remove the folder, OneNote, and stop being asked to install OneNote when I do a copy.
Thanks!

I just noticed the number of programs running in the System Tray is fewer than normal. I will do a restart and update this post if anything noteworthy happens.

After restarting, the OneNote desktop folder disappeared. The number of programs in the System Tray looks normal.
OneNote does not appear to be running.
I'll update this thread if it comes back.

Just a note, it's possible to have 2 versions of OneNote, one that comes with Microsoft Office and another that came with Windows. The Notebook I'm on now does not have Office but was upgraded from Win10 to Win11 and has OneNote for Windows 10.

OneNote can be installed as a web app and a standalone desktop app; its also part of the Microsoft Office suite.

Unlike the rest of the Microsoft Office, it has always been free.

I have MS Office 2007 on my W10 and W11 computers. Office 2007 comes with OneNote as part of the office suite. It says that I can uninstall it, but I haven't bothered yet. It just sits there and doesn't do anything. I just ignore it.
