Completely Remove Apps and Programs from Windows
App uninstallation does not mean that those apps are gone completely. It leaves behind many unwanted residual files, registry entries, and temporary data that take up space and slow down your system. To completely remove that application and its traces, follow these methods to keep your system clean and clutter-free.
Why Completely Remove Programs in Windows?
Some residual files might come in handy if you're thinking of reinstalling a particular application; they may contain settings and configurations. For the case that you've decided you wouldn't need that software anymore, get rid of its fragments to avert unnecessary consumption of space and possible clash.
If an application has ever caused trouble on your system, then; it would bring the same problems back with no deletion of the leftover files. Deleting all these would assure a cleaner installation and better performance.
1. Remove Registry Entries
Most of the important data for every application, such as user preferences, licenses, and trial information, is saved in the Windows registry. Unfortunately, these entries may usually be left behind once the applications are uninstalled.

Navigate to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\
Find a folder related to the uninstalled app.
Right-click on it and select Delete.
Click Yes to confirm the deletion.
⚠ Tip: Always create a backup of the registry before you make any change. This can be done by selecting the option File > Export within the Registry Editor.
