VirtualBox guest showing programs in the host VM that are installed on the host. What is this setting?

[waveform]

VirtualBox is installed on my host Windows 10 machine.

Why are applications on the host showing up on the guest's desktop in the VM?

I have a VM/guest running Win11. When I load the guest VM I'm seeing programs that are installed on my windows 10 host OS. I'm just using the VM to open and test files from the internet before I install them. How can I cut the guest off from accessing application resources on the host? I've never seen this behavior and It feels like a security vulnerability. What setting is causing this? An AI bot mentioned that it could have something to do with seamless mode, but that is grayed out. I can't change that setting if that is in fact the issue. I want the VM to be totally isolated from my host with the shared folders being the exception.

Did you sign in with onedrive? It's probably just an icon sync.

No, I just installed VirtulBox and then installed windows 11 as the guest. When I booted to the desk top of the guest, I noticed LibreOffice and Notepad++ and AvidMux and some other software I use for different tasks. I'm sitting here asking myself, "how the hell does this guest know what I have on my host?" One of the most useful aspects of a VM is being able to isolate an OS from your host OS. I know there are other reasons for a VM, but this was surprising as a default feature to enable. An AI bot mentioned that it could have something to do with seamless mode, but that is grayed out. I can't change that setting if that is in fact the issue. I don't know though.

EDIT
I see what's going on. A few months ago I tried slip streaming a few programs into the ISO and then never used it. I ran that ISO by accident. VB is ok, I grabbed the wrong image when I installed it.
