Yesterday, when i was working late a friend messaged me in a panic: "I just asked Copilot a bunch of personal questions… and now I’m worried it’s all saved somewhere!" (I shouldn't say this, but in case if you are curious what it was, as per his discussion looks like he asked relationship advice 😂) To his surprise, when he dug a little deeper, he also found every single search he’d done since March sitting there. The best — and worst — part? He’s actually privacy‑savvy. He never even signed in to Copilot.microsoft.com, yet the chats and searches were still saved offline on his PC.
He’s not alone. Every week, thousands of people search for things like how to delete Copilot chat history, clear Copilot data, or even how to delete Copilot chat when not logged in. The truth is, Copilot can store your conversations — but the good news is, you have full control over what stays and what goes.

Option 2: Delete All Activity History
This is the “wipe it clean” button.

How to Delete Copilot History in Microsoft 365 Apps (Word, Excel, PowerPoint, OneNote) ?

How to delete Copilot chat when not logged in?
You might be wondering: “I’ve got a ton of Copilot conversations saved on my PC, but I never even signed in to my Microsoft account. I’ve been using Copilot offline — so how do I clear everything at once without deleting chats one by one?”
Here’s the deal — even if you’re not signed in, Copilot can still store your chat history locally on your Windows device. This means it’s sitting in your PC’s cache or temporary files, not in your online Microsoft account.
My preferred method which is deleting browsing history of Edge.
You might ask why to delete Microsoft Edge. Copilot at the time of writing this post, i found was using the Microsoft Edge only as backend, you can even verify that, by right clicking on your copilot app, select anything like inspect something, it will open in Microsoft edge (even when your default browser might be some other one). So, this is easy method.
Why this works: The Windows Copilot app is powered by the Microsoft Edge browser. Even when it runs as a separate application, its conversations are stored as part of Edge's browser cache. By clearing this cache, you're clearing Copilot's "short-term memory."
first, Open Microsoft Edge
On Windows 10 or 11, look at the bottom‑left of your screen for the Start button (the little Windows logo).
Click it, then start typing Edge.
You’ll see Microsoft Edge appear in the search results — click it to open.
(Tip: If you see an “e”‑shaped blue‑green swirl icon on your desktop or taskbar, that’s Edge. You can click that too.)
In the top‑right corner of Edge, you might see a little profile icon (if you had signed in), Click the three dots (⋯) in the top‑right corner of Edge which when clicked when tell new tab, history, bookmarks,etc. Select delete browsing history -> All time. That's it.
