How to uninstall Edge Dev on Windows
Save Edge Dev browsing data before uninstalling that channel, and leave stable Edge in place.
Quit the app
Close Edge Dev and any work it is running, then use Task Manager (Ctrl+Shift+Esc) to check for its remaining processes.
Use its uninstaller
Open Settings › Apps › Installed apps, find Edge Dev and choose Uninstall. Use the vendor uninstaller rather than deleting its program folder.
winget uninstall --id Microsoft.Edge.Dev --exact
For this installation, winget invokes the registered removal method. It is not a separate cleanup of user data. Windows may ask for administrator approval.
Check the result
winget list --id Microsoft.Edge.Dev --exact
Test-Path -LiteralPath "${env:LOCALAPPDATA}\Microsoft\Edge Dev" -ErrorAction Stop
Read winget's result as well as its exit status: an explicit no-installed-package result concerns only this package, while a source, access or query error leaves the answer unknown. A successful Test-Path returning True means that exact location remains; False means it is absent. Neither result checks other paths. The commands do not delete anything.
What Mole lists
| Location | Item | Default |
|---|---|---|
%LOCALAPPDATA%\Microsoft\Edge Dev |
Personal data; back up before removal | Listed but not selected |
%ProgramData%\Microsoft\Windows\Start Menu\Programs\Microsoft Edge Dev.lnk |
Shortcut | Selected by default |
%PUBLIC%\Desktop\Microsoft Edge Dev.lnk |
Shortcut | Selected by default |
HKCU\SOFTWARE\Microsoft\Edge Dev |
Registry entry | Listed but not selected |
The later retest listed the Dev profile and its registry key. The key was removed and the profile stayed unselected on disk. Stable Edge and other channel folders were not listed. Current Select all can select the Dev profile despite its default-off state.
These defaults assume Remove data and settings with apps is off. Explicit Select all or Also remove user data can include the listed personal-data rows. Check the selection before confirming. Selected files that Mole removes go to the Recycle Bin; selected registry entries are backed up before removal. The vendor uninstaller has its own deletion behavior.
What this test covered
Recorded on 2026-10-20: Edge Dev, version 157.0.4329.0, machine-wide, MSI, winget package Microsoft.Edge.Dev. The evidence comes from an ARM64 Windows test environment and a development build of Mole. It does not certify the current downloadable package or removal of real signed-in accounts, synchronized data or production projects.
