How to uninstall TeamSpeak on Windows

Your TeamSpeak 3 identity is what servers know you by, and it lives only in %APPDATA%\TS3Client together with your bookmarks and settings, unless you back it up to a myTeamSpeak account. Export it before you remove anything: Tools › Identities, select your identity, Export. Losing it means losing the permissions servers granted to it. This guide covers TeamSpeak 3 Client installed per-user from the TeamSpeakSystems.TeamSpeakClient winget package.

Quit TeamSpeak first

Disconnect, then quit from the Connections menu or the tray icon. Check Task Manager (Ctrl+Shift+Esc) for any ts3client_win64.exe still listed. If an overlay such as TeamSpeak Overlay or Overwolf was installed alongside, quit it too: it installs as a separate app and can keep TeamSpeak's folders open.

Remove the app with its own uninstaller

Go to Settings › Apps › Installed apps, find TeamSpeak 3 Client, and choose Uninstall, or run:

winget uninstall --id TeamSpeakSystems.TeamSpeakClient

An overlay installed with it has its own entry in Installed apps; remove it there separately if you do not use it.

Where the data lives

Check the result

Run these read-only commands after the uninstall finishes:

Get-Process ts3client* -ErrorAction SilentlyContinue
winget list --id TeamSpeakSystems.TeamSpeakClient
Test-Path "$env:LOCALAPPDATA\Programs\TeamSpeak 3 Client"
Test-Path "$env:APPDATA\TS3Client"
Test-Path "HKCU:\Software\Classes\ts3server"

• No output from Get-Process only means this query observed no matching process; a suppressed error leaves the running state unknown.
• A completed winget list query with no match means the package record is gone; a matching row means the uninstall did not finish.
• Test-Path on the program folder returning True after the uninstall means something still had files open there; quit any overlay, restart Windows, and check again.
• Test-Path "$env:APPDATA\TS3Client" returning True means your identity and settings are still there, which is expected unless you removed them yourself.
• Test-Path on the ts3server key returning False means the link registration is gone.

If you installed it with winget

winget uninstall runs the same uninstaller Settings › Apps uses; it does not touch %APPDATA%\TS3Client.

Account

Uninstalling does not delete a myTeamSpeak account, any server you rent, or your identity on servers you joined.

What Mole lists

For TeamSpeak 3 Client installed per-user from winget:

• The program folder, the desktop and Start Menu shortcuts, and a row grouping Windows' own records of when you opened the program are selected by default.
• The ts3server, ts3file and ts3addon links are selected by default and backed up to a .reg file before removal.
• %APPDATA%\TS3Client and %LOCALAPPDATA%\TeamSpeak 3 are listed but not selected, since the first holds your identity.
• HKCU\Software\TeamSpeak 3 Client is listed but not selected.
• If another process still has one of these folders open, Mole names that process on the row and leaves the folder in place; when the hold is an open file, it tries again in the background for a minute first.

What this test covered

Tested on September 28, 2026 with TeamSpeak 3 Client 3.6.2 installed through winget, per-user scope, on an ARM64 test VM. The test installed it from an elevated session, so its uninstaller asked for administrator access; a normal per-user install does not. The first run left the program folder and %APPDATA%\TS3Client on disk. In the latest recorded rerun, the program folder was already removed, but %APPDATA%\TS3Client remained and was not a review row in that run. Not verified: a myTeamSpeak account and identity restore.
