So about a year ago, I paid (or made my employer pay) 4000 USD to get an AI-PC. That laptop had no AI features whatsoever, so its NPU is still in brand new condition. Great savings abound if I ever end up selling it! đ
But about 6 months later, that pc got its first AI feature â the standalone Copilot app. I mean, I never got the fabled native app that actually integrated with Windows. Mine was always just a wrapper around âBing Chatâ, and didnât use the NPU in any way â but hey, it still counts, right?
Now, all that was true for about 6 months. Or more accurately, until yesterday.
This article explains where your (or at least mine) Copilot went, speculation on why it did that, and how to get it back.
Background
Yesterday (at the time of writing â 10.3.2025), my Copilot ceased to exist.
Why do I know?
Because paying thousands of dollars yielded me something that most people still donât know they need: a dedicated Copilot-key. And after months of working without major issues, the key suddenly stopped working.
I actually use that key and itâs a bummer if it doesnât work.
Itâs only the second time that happens (first one was when Microsoft first rolled out the option to select what that key does, and also apparently set it to ânullâ), so I am not yet used to the button not doing anything again.
Checking the configuration in Control Panel Settings, it looks like thereâs nothing bound to the key and nothing I even could bind to it:


Whatâs up with this now?
Where did my Copilot go?
The official story is that the March 2025 Security Patch for Windows 11 and Windows 10 removes the Copilot app (and of course unpins it from your task bar, too). So in a way, itâs to be expected.
Microsoft puts it like this:
Weâre aware of an issue with the Microsoft Copilot app affecting some devices. The app is unintentionally uninstalled and unpinned from the taskbar.
Note: This issue has not been observed with the Microsoft 365 Copilot app.
The KB numbers for different flavors of the Operating System are:
- Windows 11 24H2 â KB5053598
- Windows 11 23H2 â KB5053602
- Windows 11 22H2 â not affected (I guess this is the most stable variant of Win 11?)
- Windows 10 â KB5053606, KB5053596, KB5053594 and KB5053618.
However â I have not gotten my March update yet. My Copilot was not uninstalled by Windows update. Iâm still on the February 2025 Patch level (the latest one to require a reinstall of my machine â€ïž)⊠So I donât think they have the whole picture here.
Anyway. We come to a conclusion: Your Copilot is gone because either Windows Update removed it, or it removed itself.
Investigation
So my Copilot wasnât gone because of Windows Update. I want to know where it went, so I dug into the Application logs in Event Viewer â and literally the only line about Copilot was the one below:

No day in the Windows world without some new excitement, it seems!
So CopilotNative.exe experienced a classic case of âapplication hangâ, around the time Windows uninstalled it. Letâs take a look at the path âC:\Program Files\WindowsApps\Microsoft.Copilot_1.25014.121.0_x64__8wekyb3d8bbwe\CopilotNative.exeâ â Whatâs in that directory?

Letâs give it a go!

Oh? Nothing?
And when trying to navigate to C:\Program Files\WindowsAppsâŠ

Ah, this again.

I decided to check the permissions for the folder:

Now, not only am I a user of this glorious 4000 USD can of bugs and spaghetti, but I also happen to be an administrator. So I should be able to list folder contents, read and execute the directory contents.
But alas, I can not.
Why? Because âthe access control is corruptâ.

Great.
So let me read that out for you once more:
âThis access control entry is corrupt. Delete it and create a new one.â
Okay then. Windows Update has just absolutely and completely fucked up again and the permissions are now broken.
On a 1-month old installation of Windows 11.
Just another day in the Windows world. And the kicker? This is apparently a a well-known and recurring issue at least since 2016. https://answers.microsoft.com/en-us/windows/forum/all/access-control-entry-is-corrupt/4e3d5500-5c7d-4839-be4f-c269705561ca
But since the rest of my âWindows Appsâ seem to work fine, Iâll have to just assume that âThis access control entry is corrupt. Delete it and create a new one.â actually just means âThis is fine. đ¶âđ„â
Iâm not going to go down the path of fixing whatever is wrong with âWindows Appsâ directory now. Besides, itâs not worth it â Windows Update would just break it soon again anyway.
Fixing my missing Copilot
This is going to be the boring part.
It doesnât matter what greater power decided you donât need the Copilot app anymore. You can simply defy fate by reinstalling the app. And since itâs just a ânativeâ wrapper of a web app, youâre not losing any data, either!
So weâll just reinstall Microsoft Copilot (Bing Chat) (Copilot) (New) by either running this in terminal:
winget install "Microsoft Copilot" --source msstore
Or navigating to the store page to install it: https://apps.microsoft.com/detail/9NHT9RB2F4HD?hl=en-us&gl=CA&ocid=pdpshare

Thatâs it! If you just wanted to fix your Copilot, youâre good to go.
Rant: If my Copilot bails out, Iâm going to start having trust issues
From a strategic point of view, this feels like a bit of a blunder from Microsoft.
If you want people to use your apps, donât ship Windows updates that uninstall them. And even more so, donât make the apps randomly disappear.
If that keeps happening â and it has happened before â users might start to have some trust issues with your apps.
And the fact that the first indication I got of Windows having fucked up was Control Panel popping up when I hit the Copilot key⊠Disappointing.
But hey! After reinstalling the app, I now have something called âCopilotNative.exeâ. Thatâs a native Copilot app, right? So it should be able to use native features of my pc â my NPU, and control my Windows, right?
Putting that NPU to use!
I wanted to check Copilot on some tips on how to use the NPU â and of course, check whether the âCopilot Nativeâ app is using my NPU.

It definitely is not. I guess I shouldnât be surprised đ
The app is ânativeâ as in, it supports alt+space as a keyboard shortcut, and itâs not a PWA, but a real app (that just happens to only be a wrapper around copilot.microsoft.com).
So I guess it canât do anything with my machine?

Or the classic:

Ah well. Time for some gaslighting then.

⊠yeah, thatâs the state of ânativeâ software development on Windows in 2025.
That said, having an NPU in my laptop is of course super helpful for the future. The future, where you need a subscription to be able to use your local hardware, that is! Like with Paint.

Since I already pay for E5 and Copilot licenses, I felt like I should maybe, just maybe, be able to use my local NPU for free in apps that support it, like Notepad and Paint⊠But I guess thatâs too much to ask for.
So far, the only way to use my NPU that Iâve found, is to use Windows Studio Effects on my built-in webcam. You know, the one that I donât use, because I have a real webcam? Although Iâve got to admit, the automatic zoom-in effect up your nostrils is fantastic, and Iâm sure itâll find plenty of use in some circles!
Iâm not saying the AI space wouldnât be incredibly exciting. Because it is!
But sometimes the teething issues feel more like âcrapping your nappyâ issues, and it feels really dismissive of Microsoft to think that I am not yet dealing with enough shit in my life, and should take some from my Copilot, too.
I mean, come on â itâs called Copilot, not âcrybaby that can make funny pictures and take meeting notesâ.
Ehh, thatâs a lame way to end an article. So hereâs an AI-powered upscaling of the face of the copilot from the illustration of this article, so we can end on a high note instead.
