Using an “Add-Remove Programs” cleaner—or more effectively, a third-party uninstaller—helps free up space by removing not just the application, but also the hidden, residual files, folders, and registry entries that standard uninstallers leave behind.
Here is how to effectively use a program cleaner to free up space: 1. Using Specialized Uninstaller Software (Recommended)
Third-party tools like Revo Uninstaller or IObit Uninstaller are superior to the built-in Windows tool because they perform a deep scan after the initial uninstall.
Select the program: Open the uninstaller tool and choose the program you wish to remove.
Run the standard uninstall: The tool will trigger the program’s own uninstaller.
Scan for leftovers: Once the standard uninstall finishes, the cleaner will offer scanning modes (Safe, Moderate, Advanced). Choose “Advanced” to find residual files and registry entries.
Delete leftovers: The tool will display leftover files and registry keys. Select all and click “Delete” or “Remove” to permanently clear them. 2. Using Windows Built-in Tools
If you don’t want to use third-party software, you can still use the native Add-Remove programs tool, though it requires manual cleanup of leftovers.
Open the menu: Press Windows Key + R, type appwiz.cpl, and hit Enter to open Programs and Features. Uninstall: Right-click the program and select Uninstall. Manual Cleanup (Optional but Recommended):
Registry: Type regedit in the Run dialog (Windows Key + R) to open the Registry Editor. Navigate to HKEY_LOCAL_MACHINE\Software and delete folders associated with the uninstalled program.
Appdata: Type %appdata% in File Explorer to find and delete leftovers in the Roaming and Local folders.
