The Windows Copilot experience described in early preview articles no longer exists. Microsoft replaced the original Windows sidebar with the Microsoft Copilot app and later changed how the Copilot key opens it.
If you are troubleshooting from an old screenshot, stop trying to restore the sidebar. Check which current Copilot experience, account and policy your device is using.
What changed
Microsoft says the legacy Copilot in Windows experience was replaced through Windows updates beginning in 2024. Its current Windows management guidance describes a Microsoft Copilot app rather than a Windows-integrated sidebar.
From the May 2025 optional Windows 11 preview release, the Copilot hardware key experience changed again. On supported commercial devices, the key, or Win+C where configured, can open a lightweight prompt box that expands into the full app. Administrators can configure or remap the key.
Feature availability still changes. Microsoft’s Copilot on Windows release notes show that Insider builds can temporarily lose features while previews are tested. Do not use an Insider screenshot as proof of what every production device has.
Consumer, work and web are different contexts
The word “Copilot” now covers several experiences.
- The Microsoft Copilot app is the desktop entry point.
- Microsoft Copilot Chat can use web grounding for an Entra work or school account.
- Users with the relevant Microsoft 365 Copilot licence can also use work grounding over Microsoft Graph data they are authorised to access.
- Consumer account behaviour and data terms differ from enterprise data protection for eligible work accounts.
Before testing, record the signed-in account, licence, Windows build, Copilot app version and whether the device is managed. Without those details, two users can truthfully report different interfaces.
Four useful checks
1. Confirm the app and account
Open the app and check the account identity. A personal Microsoft account is not evidence of the protections or work grounding available to a Microsoft Entra account.
For business use, confirm the organisation has approved the experience and that the intended user sees the correct web or work scope.
2. Check the Copilot key
On supported devices, users may be able to change the Copilot key under Settings > Personalisation > Text input > Customise Copilot key on keyboard. Managed organisations can set policy instead.
If the app is absent from the picker, Microsoft advises checking that the current Microsoft Copilot app is installed. Do not apply random registry changes copied from an old preview guide.
3. Test data boundaries
Use harmless material. Confirm whether the response is grounded in the web or in authorised work data. Review the cited sources instead of assuming the answer is current.
Microsoft states that work-grounded Copilot only shows data the user has permission to access. That makes existing Microsoft 365 access governance important; it does not mean every accessible file is appropriate or accurate.
4. Check admin controls
Administrators can manage pinning, app access and the Copilot hardware key through supported Windows and Microsoft 365 controls. AppLocker is one documented control for the app experience.
Test policy on a pilot group before broad deployment. A policy applying successfully does not prove that users understand which data context they are in.
What not to expect from the old preview
Early articles showed the sidebar toggling Windows settings and summarising an open Edge page. Those observations belonged to a preview that Microsoft replaced.
Do not promise that the current app can perform every old demo, inspect any open page automatically or change system settings. Capabilities vary by release, account, region and admin configuration.
Boundaries checked on 24 August 2026
This article reflects Microsoft’s Learn documentation and Windows Insider release notes available on that date. Preview features can change or disappear. Licensing and availability should be checked against the tenant and current Microsoft product terms before rollout.
The checks above prove only the tested device, account and policy combination. They do not prove organisation-wide deployment, data readiness or compliance.
