How to uninstall Greenshot on Windows

Greenshot is a screenshot tool with almost no data of its own: its settings file is a handful of hotkeys and destinations, not a library you need to plan around. This guide covers Greenshot installed machine-wide from the Greenshot.Greenshot winget package.

Quit Greenshot first

Greenshot runs from the tray and starts automatically at sign-in (Settings › Apps › Startup, look for "Greenshot"). Check Task Manager (Ctrl+Shift+Esc) for Greenshot.exe and close it before you uninstall; since this is a machine-wide install, removing it needs an administrator.

Remove the app with its own uninstaller

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

winget uninstall --id Greenshot.Greenshot

Where the data lives

Location	What it holds	What to do
`%LOCALAPPDATA%\Greenshot`	A log file and the last screenshot it saved	Safe to remove
`%APPDATA%\Greenshot`	`Greenshot.ini`, your hotkeys, output folder and any FTP or cloud destinations you set up	Back this up if you customized those settings; otherwise safe to remove

Windows also keeps a small .greenshot file-type registration and a generic Greenshot entry under its own Classes keys after the app is gone; these are shared file-association records, not Greenshot's own data, and need no action from you.

Check the result

Run these read-only commands after the uninstall finishes:

Get-Process Greenshot -ErrorAction SilentlyContinue
winget list --id Greenshot.Greenshot
Test-Path "${env:ProgramFiles(x86)}\Greenshot"
Test-Path "$env:LOCALAPPDATA\Greenshot"
Test-Path "$env:APPDATA\Greenshot"

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.
The first Test-Path returning False means the program folder is gone; True means files remain there.
The next two returning True means the log or settings file is still there, which is expected unless you removed them yourself.

If you installed it with winget

winget uninstall runs the same Inno Setup uninstaller Settings › Apps uses and removes the same program files; it does not touch %LOCALAPPDATA%\Greenshot or %APPDATA%\Greenshot on its own, though in this test the uninstaller did clear the startup entry itself.

What Mole lists

For Greenshot installed machine-wide from winget:

The program folder and the public Start Menu folder (the app shortcut plus its readme and license shortcuts) are selected by default.
%LOCALAPPDATA%\Greenshot and %APPDATA%\Greenshot are listed but not selected, since the settings file may hold destinations you configured.
Greenshot's own screenshot-editor registration under HKCU\Software\Classes\CLSID is selected by default and backed up to a .reg file before removal.
The shared .greenshot file-type key and the generic Greenshot Classes entry are not this app's own data and are left alone.

What this test covered

Tested with Greenshot 1.3.315 installed through winget, machine scope, x86 Inno Setup package. Not verified: custom hotkeys, FTP or cloud upload destinations, and OCR or other plugins.
