What to Uninstall Before You Try a New Manager

Two clipboard managers running on the same Windows machine is the most common cause of clipboard weirdness. Copies appear in one history but not the other. Paste targets receive stale content. The Windows clipboard history (Win+V) and a third-party manager disagree about what is "current." The fix is to fully uninstall the old manager before installing the new one. "Uninstall" here means more than running the uninstaller: it means removing the running process, the startup entry, the history files, and any leftover registry keys that re-launch the app on login. This article is that checklist.

For the trial that follows the uninstall, see how to trial a clipboard app for seven days. For the agency context where multiple tools may coexist by design, see agency stack: designers, PMs, and devs differ and can you run two clipboard tools at once.

Why a full uninstall matters

The Windows clipboard is a shared OS surface. Any app can register as a clipboard format listener and receive every copy. When two clipboard monitors run at the same time, both receive every copy, but they may write to their own history stores at slightly different times. The result is that the "current" clipboard content visible to a paste target can be the one written by whichever monitor wrote last, which is not always the monitor the user expects.

The same problem applies to drag-out and to hotkeys. Two clipboard managers both registering Alt+C will produce a conflict that Windows resolves by sending the keystroke to whichever app registered last. Two clipboard managers both trying to provide drag-out from history may produce a drag that the destination app rejects. The clean fix is one clipboard monitor at a time, plus the Windows built-in Win+V (which does not conflict because it is invoked on demand, not as a continuous listener in the same sense).

For the longer treatment of the conflict itself, see two clipboard managers fighting each other.

Step 1: quit the running process

Before running any uninstaller, quit the running clipboard manager. Most clipboard managers run as a tray icon, so right-click the tray icon and choose Exit or Quit. If the tray icon is hidden, click the overflow chevron in the taskbar to find it. If the app does not have a tray icon, open Task Manager (Ctrl+Shift+Esc), find the process on the Processes tab, right-click, and choose End task.

The reason this matters: many uninstallers will not remove files that are in use. If the clipboard manager is still running, the uninstaller will leave the running process and the files it has open, and the next login will re-launch the app from those leftover files.

Step 2: check the startup entries

Clipboard managers almost always register a startup entry so they launch on login. The uninstaller should remove the entry, but not all do. Before running the uninstaller, note the startup entries so they can be checked after.

Two places to check on Windows 11:

1. Task Manager → Startup apps tab. Look for the clipboard manager's name. Right-click and Disable if present.
2. Settings → Apps → Startup. Same list, different view.

Two more places to check that the UI does not surface:

• shell:startup — paste into File Explorer's address bar. This opens the per-user Startup folder. A shortcut placed here launches on login.
• shell:common startup — the all-users Startup folder. A shortcut here launches on login for every user.

Delete any shortcut for the clipboard manager from both folders. Some older clipboard managers (ClipX, ArsClip) use these folders instead of the registry-based startup list.

Step 3: run the uninstaller

Open Settings → Apps → Installed apps. Search for the clipboard manager's name. Click the ... menu (Windows 11) or click the app (Windows 10) and choose Uninstall. Follow the uninstaller's prompts.

Two things to watch for:

• "Keep your settings?" prompts. Some uninstallers offer to keep settings, history, or config files. For a clean trial of the new manager, choose "remove everything" or "no, delete all data." If the prompt is unclear, choose the more aggressive option.
• "Reboot now?" prompts. Some uninstallers require a reboot to release files. Reboot when asked; do not postpone.

After the uninstaller finishes, do not install the new manager yet. The next steps verify the uninstall was complete.

Step 4: verify the process is gone

Open Task Manager again and check the Processes tab. The clipboard manager should not appear. If it does, the uninstaller failed to remove it; right-click and End task, then check the install directory in the next step.

Also check the Details tab in Task Manager, which shows processes that the Processes tab may aggregate. Sort by Name and look for the clipboard manager's executable name.

Step 5: delete the install directory

The uninstaller should remove the install directory, but not all do. Check the typical install locations:

• C:\Program Files\ and C:\Program Files (x86)\ — for machine-wide installs.
• %LOCALAPPDATA%\Programs\ and %LOCALAPPDATA%\ — for per-user installs (common for Electron apps).
• %APPDATA%\ — for some older apps.

Delete the clipboard manager's folder if it remains. If Windows refuses to delete a file because it is in use, reboot and try again. If the file is still in use after a reboot, the clipboard manager is still being launched by a startup entry or a scheduled task; resolve that first.

Step 6: delete the history and config files

This is the step most users skip and the one that matters most for a clean trial. Clipboard managers store history and config under the user profile, and these files survive uninstall:

• %APPDATA%\AppName\ — common config and history location.
• %LOCALAPPDATA%\AppName\ — common cache and large-payload location.
• %LOCALAPPDATA%\Packages\ — for Microsoft Store apps, look for the app's package family name folder.

Delete these folders. The new clipboard manager should start with an empty history, not a stale copy of the old manager's data. If the new manager imports the old history by accident, the user may paste content they thought was gone.

For the broader privacy argument, see how to wipe clipboard data before selling a PC.

Step 7: clear the Windows clipboard history

The Windows clipboard history (Win+V) is a separate surface from any third-party manager. Clearing it removes any content the old manager left behind that Win+V also captured:

1. Press Win+V to open the history flyout.
2. Click the ... menu (or the broom icon, depending on Windows version) and choose "Clear all" or "Clear clipboard data."
3. Confirm.

Alternatively, open Settings → System → Clipboard → Clear clipboard data → Clear. This clears all unpinned entries; pins survive. If the old manager left pinned entries that are no longer wanted, delete them individually from Win+V → ... → Delete.

For the full breakdown, see how to clear clipboard history on Windows 11.

Step 8: reboot

A final reboot clears any clipboard format listeners that were registered by the old manager and not yet released. It also clears the live clipboard (the single-item clipboard that holds the most recent copy). After the reboot, the machine is in a clean state for the new trial.

A one-page checklist

Special cases

Microsoft Store apps

Microsoft Store apps uninstall through Settings → Apps → Installed apps, but they also leave a package data folder under %LOCALAPPDATA%\Packages\. Find the folder whose name matches the app's package family name (usually a long string like AppName.Publisher_3hb...) and delete it. The folder is recreated if the app is reinstalled, so deletion is safe.

Portable apps

Portable clipboard managers (ClipX, ArsClip, some Ditto builds) do not have an uninstaller. To remove: quit the process, delete the folder the app was extracted to, and remove any startup shortcut from shell:startup. History and config are usually in the same folder as the executable, so deleting the folder removes everything.

Electron apps with auto-update

Electron-based clipboard managers (Edge-Drop, some CopyQ builds) may run an auto-updater service in the background. Check Task Manager → Details for any process with "Update" in the name belonging to the app. If present, end the task and delete the updater's install folder (often under %LOCALAPPDATA%\AppName\Update\).

Leftover scheduled tasks

Some clipboard managers register a scheduled task to relaunch on login or on a schedule. Open Task Scheduler (taskschd.msc), look under Task Scheduler Library for the app's name, and delete any task that belongs to it. This is rare but worth checking if the app keeps reappearing after reboot.

Verifying a clean state

After the eight steps above, the machine should be in a clean state for the new trial. The verification:

• Task Manager shows no process for the old manager.
• Task Manager → Startup apps shows no entry.
• shell:startup and shell:common startup show no shortcut.
• Settings → Apps → Installed apps does not list the old manager.
• %APPDATA%\ and %LOCALAPPDATA%\ do not contain the old manager's folder.
• Win+V shows an empty history (or only deliberate pins).
• A reboot does not auto-launch the old manager.

If all seven checks pass, the machine is ready for the new trial. The next step is how to trial a clipboard app for seven days.
