Uninstalling software in Windows often leaves behind residual files, folders, and registry entries. These leftovers can accumulate over time, wasting disk space and occasionally causing conflicts with future installations. While Windows built-in uninstaller—the Programs and Features pane removes the core application, it rarely performs a thorough cleanup.
Wise Program Uninstaller addresses this issue with a smart automation feature. Once enabled, it ensures that every uninstallation is followed by a deep cleanup scan—no matter which uninstaller is used. This article explains how to enable auto leftover scanning in Wise Program Uninstaller to scan for leftover files automatically after other uninstallers remove an app.
How to Enable Automatic Leftover Scanning
Step 1. Launch the software
Open Wise Program Uninstaller.
If you haven’t had Wise Program Uninstaller on your system, click the link to download and install the latest version from its official website.
Step 2. Open Settings
Then, click the Menu icon in the top-right corner, and select Settings from the drop-down menu.

Step 3. Select Auto Scan
In the Settings panel, check the box for Prompt to scan for leftover files after other uninstallers remove an app to enable the auto scanning feature.
Close the Settings window by clicking OK.

Step 4. Scan and Clean Leftovers
Now, every time you uninstall an app using any method (Windows or third-party), a prompt appears showing the scanning results for leftover files.
Keep clicking on the Cleanup Now option to clean up the detected leftovers.

Note please: This works quietly in the background and only requires minimal interaction.
Final Thoughts
By ensuring each download is completely and automatically clean, it turns Wise Program Uninstaller into a system-wide cleanup companion, not just a standalone uninstaller. This small setting truly delivers outsized value.
