How to uninstall Postman on Windows

Check whether you are signed in to a Postman account before removing the app: signed-in collections and environments sync to your account and can be reopened after reinstalling, but anything you built while signed out lives only in this PC's local folder and is gone once that folder is deleted. This guide covers Postman installed per-user from the Postman.Postman winget package, which installs the same app as Postman's own download.

Check what is local-only before removing anything

Open Postman and look at whether you are signed in, top right. If you are not signed in, everything you built lives only on this PC; sign in first if you want it saved to your account, or treat the local folder below as the only copy you have. Postman's guide to the offline API client explains what still works without an account or network connection.

Quit Postman first

Finish or cancel any running requests, then quit Postman from its window or tray icon. Postman runs several processes, one per window plus helpers, so check Task Manager (Ctrl+Shift+Esc) for any Postman.exe still listed before you uninstall.

Remove the app with its own uninstaller

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

winget uninstall --id Postman.Postman

Where the data lives

Postman's own support article warns that if you use it locally without signing in, do not delete %APPDATA%\Postman outright: rename it first, reopen Postman to create a fresh one, and only delete the renamed copy once you have confirmed you do not need anything in it. How to remove local data

Check the result

Run these read-only commands after the uninstall finishes:

Get-Process Postman -ErrorAction SilentlyContinue
winget list --id Postman.Postman
Test-Path "$env:LOCALAPPDATA\Postman"
Test-Path "$env:APPDATA\Postman"

• No output from Get-Process only means this query observed no matching process; a suppressed error leaves the running state unknown. A listed process means a window or helper is still open.
• 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.
• Test-Path "$env:APPDATA\Postman" returning True means your local collections and history are still there, which is expected unless you removed them yourself.

If you installed it with winget

winget uninstall runs the same uninstaller Settings › Apps uses and removes the same program files; it does not touch %APPDATA%\Postman or %USERPROFILE%\Postman on its own.

Account and sync

Uninstalling does not sign you out of your Postman account or delete anything already synced there. If you were signed in, your collections and environments reapply the next time you sign in on any machine, whether or not you remove the local folders above.

What Mole lists

For Postman installed per-user from winget:

• The program folder and both the Desktop and Start Menu shortcuts are selected by default.
• %APPDATA%\Postman, where your local collections and history live, is listed but not selected; the caches inside it are listed as their own rows and selected by default.
• %USERPROFILE%\Postman is listed but not selected.
• If a postman:// link registration still points at the removed program, Mole lists it too, after backing it up to a .reg file.

What this test covered

Tested with Postman 12.29.2 installed through winget, per-user scope. Every listed row was ticked and removed in this test. Not verified: removing an install with local-only (signed-out) data, and a signed-in account.
