How to uninstall AnythingLLM on Windows

Everything AnythingLLM Desktop builds up lives in %APPDATA%\anythingllm-desktop, in its storage folder: the database with your workspaces, chats and settings, the parsed documents you uploaded, the local vector database, custom agent skills and any models downloaded for its built-in runner. Models can make it many gigabytes, and the uninstaller leaves the folder in place. Models can be downloaded again, but your workspaces, documents and agent skills cannot, so copy the whole folder to another drive before you remove it. If you pointed AnythingLLM at Ollama or LM Studio instead, those models belong to that app and stay where it keeps them. This guide covers AnythingLLM installed per-user from the official installer at anythingllm.com. AnythingLLM desktop storage

Quit AnythingLLM first

Quit AnythingLLM from its window. It runs as several AnythingLLM.exe processes, so check Task Manager (Ctrl+Shift+Esc) for any still listed before you uninstall. The test found no startup entry.

Remove the app with its own uninstaller

Go to Settings › Apps › Installed apps, find AnythingLLM, and choose Uninstall. The uninstaller removes the program folder in %LOCALAPPDATA%\Programs\AnythingLLM, which carries the built-in inference engine and is well over a gigabyte on its own. It does not touch %APPDATA%\anythingllm-desktop. AnythingLLM uninstall

Where the data lives

Location What it holds What to do
%APPDATA%\anythingllm-desktop storage with the database, documents, vector data, agent skills and downloaded models Back up the whole folder if you might reinstall; remove it only when you no longer need your workspaces
%LOCALAPPDATA%\anythingllm-desktop-updater Downloaded update installers Safe to remove
HKCU\Software\Classes\anythingllm The anythingllm:// link, still pointing at the removed program Safe to remove once the app is gone
%LOCALAPPDATA%\prisma-nodejs\Cache and %APPDATA%\Prisma\master Database engine caches its server wrote in this test; any project that uses Prisma writes the same folders Leave them if you use Prisma; otherwise they are caches and safe to remove

Firewall rules

If you allowed AnythingLLM through the Windows Security alert, Windows created two inbound rules named anythingllm.exe, and the uninstaller leaves them. They point at a program that no longer exists. To remove them, open Windows Defender Firewall with Advanced Security › Inbound Rules as an administrator and delete the two anythingllm.exe rules.

Check the result

Run these read-only commands after the uninstall finishes:

Get-Process AnythingLLM -ErrorAction SilentlyContinue
Test-Path "$env:LOCALAPPDATA\Programs\AnythingLLM"
Test-Path "$env:APPDATA\anythingllm-desktop"
Test-Path "$env:LOCALAPPDATA\anythingllm-desktop-updater"
Test-Path "HKCU:\Software\Classes\anythingllm"
Get-NetFirewallRule -DisplayName "anythingllm.exe" -ErrorAction SilentlyContinue | Select-Object DisplayName, Direction, Action
  • No output from Get-Process only means this query observed no matching process; a suppressed error leaves the running state unknown. A listed process means something is still open.
  • The first Test-Path returning False means the program folder is gone; True means files remain there.
  • Test-Path "$env:APPDATA\anythingllm-desktop" returning True means your workspaces and models are still on disk, which is expected if you kept them. False means they are gone.
  • The updater and link Test-Path lines returning True mean those items are still there; False means they are gone.
  • The last command printing rows means the firewall rules are still there. No matching output from a confirmed successful query means they are gone.

What Mole lists

For AnythingLLM installed per-user from the official installer:

  • The program folder goes with the app row.
  • %LOCALAPPDATA%\anythingllm-desktop-updater, which holds only downloaded update installers, is selected by default.
  • %APPDATA%\anythingllm-desktop is listed but not selected, since your workspaces live there. Ticking it, yourself or with Also remove data, sends them and any downloaded models to the Recycle Bin, and a large folder may be too big for the Recycle Bin, in which case Windows asks before deleting it for good.
  • The desktop and Start Menu shortcuts, the anythingllm:// link and a row grouping Windows' own records of when you opened the program are selected by default; the link is backed up to a .reg file before removal.
  • The two firewall rules are named in the result and not removed; remove them yourself as above.
  • The Prisma cache folders are not listed, since other projects share them.

What this test covered

Tested on September 29, 2026 with AnythingLLM 1.16.2 from the official installer, per-user scope, installed from an elevated session on an ARM64 virtual machine. The uninstaller is NSIS and ran silently. Every listed row was ticked and removed in this test; the firewall rules and the Prisma cache folders stayed. No workspace was set up, no document was embedded and no model was downloaded, so backing up or removing a working setup was not verified.
