Remove "Ask Copilot" from the right-click menu — via Mauro Huculak, Pureinfotech

The easy way

1. Simplest fix if you don't use Copilot at all: uninstall it (Settings → Apps → Installed apps → Copilot → Uninstall), which removes the item too.

Registry change

Double-click a .reg file and confirm to merge it. Right-click → Edit first if you want to read it, which is always a good idea with any .reg file from the internet.

Apply

Windows Registry Editor Version 5.00

; Oddbyte.Me: Remove "Ask Copilot" from the right-click menu

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked]
"{CB3B0003-8088-4EDE-8769-8B354AB2FF8C}"="Ask Copilot"
"{ED215C26-C810-49CE-929E-31D7E83A82E9}"="Ask Copilot"

Undo

Same thing from a command prompt

Run in a normal (non-admin) Command Prompt or Terminal.

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked" /v "{CB3B0003-8088-4EDE-8769-8B354AB2FF8C}" /t REG_SZ /d "Ask Copilot" /f
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked" /v "{ED215C26-C810-49CE-929E-31D7E83A82E9}" /t REG_SZ /d "Ask Copilot" /f

Undo:

reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked" /v "{CB3B0003-8088-4EDE-8769-8B354AB2FF8C}" /f
reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked" /v "{ED215C26-C810-49CE-929E-31D7E83A82E9}" /f

The first ID is the one Pureinfotech documented for the 2025 Copilot app; XDA (April 2026) lists {ED215C26-C810-49CE-929E-31D7E83A82E9} as the current one. Blocking an ID that isn't installed does nothing harmful. If the item comes back after a Copilot update, the ID has probably changed again: uninstalling Copilot is the reliable fix. For all users, use the same values under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked (needs admin).
