How to uninstall TeamViewer on Windows

End any remote session before you remove TeamViewer, and tell anyone who reaches this PC through it that it will stop answering. If the PC belongs to a TeamViewer account or a company, check with the account owner or IT first, since a managed install may be removed centrally. This guide covers TeamViewer installed machine-wide from the TeamViewer.TeamViewer winget package, which uses a Windows Installer package.

Quit TeamViewer first

Close the TeamViewer window and quit it from its tray icon. TeamViewer also installs a Windows service, TeamViewer_Service.exe, which shows in Mole's Startup list rather than in Settings › Apps › Startup. The uninstaller stops and removes it; check Task Manager (Ctrl+Shift+Esc) afterwards for any TeamViewer process.

Remove the app with its own uninstaller

Go to Settings › Apps › Installed apps, find TeamViewer, and choose Uninstall, or run:

winget uninstall --id TeamViewer.TeamViewer

This is a machine-wide install, so Windows asks for administrator access. TeamViewer's own article covers uninstalling on Windows.

Where the data lives

Location	What it holds	What to do
`%ProgramFiles%\TeamViewer`	Program files; in this test two log files and an empty `ErrorReports` folder stayed after the uninstall	Check it after the uninstall and remove what is left
`%LOCALAPPDATA%\TeamViewer`	Per-user data, with a `logs` folder	Keep it if you will reinstall; otherwise safe to remove
`HKCU\Software\TeamViewer`	Per-user settings	Removed by the uninstaller in this test
Start Menu and public desktop shortcuts	Shortcuts	Removed by the uninstaller

Check the result

Get-Process TeamViewer* -ErrorAction SilentlyContinue
Get-Service TeamViewer -ErrorAction SilentlyContinue
winget list --id TeamViewer.TeamViewer
Test-Path "$env:ProgramFiles\TeamViewer"
Test-Path "$env:LOCALAPPDATA\TeamViewer"

If both Get-Process and Get-Service succeed without suppressed errors, no output means no TeamViewer program or service is left. A listed service means the uninstall did not finish; restart and run the uninstaller again.
A completed winget list query with no match means the package record is gone.
Test-Path "$env:ProgramFiles\TeamViewer" returning True means the folder with the leftover logs is still there; it holds nothing the program needs any more.
Test-Path "$env:LOCALAPPDATA\TeamViewer" returning True means your per-user data is still there, which is expected unless you removed it yourself.

If you installed it with winget

winget uninstall runs the same Windows Installer uninstall that Settings › Apps uses and removes the same things; it does not touch %LOCALAPPDATA%\TeamViewer or the logs left in the program folder.

Account and subscription

Uninstalling does not cancel a TeamViewer subscription, and a PC assigned to your account stays in its device list. Remove it from the device list in TeamViewer's web console if you no longer use it.

What Mole lists

For TeamViewer installed machine-wide from winget:

The Start Menu and public desktop shortcuts are selected by default.
%LOCALAPPDATA%\TeamViewer is listed but not selected; its logs folder is listed on its own and selected by default.
HKCU\Software\TeamViewer is listed but not selected, and backed up to a .reg file before removal.
In this test %ProgramFiles%\TeamViewer, with the two log files and the empty ErrorReports folder the uninstaller left, was not listed; check it and remove it yourself after the uninstall.

What this test covered

Tested on September 28, 2026 with TeamViewer 15.81.6 installed through winget, machine scope, removed with its Windows Installer package. Every listed row was ticked and removed in this test. Not verified: a signed-in account, an assigned or managed device, or an active remote session during removal.
