I was on a customer’s computer the other day and did a search in File Explorer, I can’t remember what for but knowing me it was a pretty basic search for say a single keyword or maybe something like *.txt in their Documents folder. IIRC they weren’t using OneDrive.
On the status bar in File Explorer, it came up with a message like “this search has been done with AI so results may not be completely accurate. Click here to give feedback”.
I just tried a search on the Win11 install on my PC and it didn’t do it. It’s possible that I’ve uninstalled Copilot on that install as I’ve been feeling increasingly militant about Edge running in the background, Game Assist, etc.
