It’s a common practice for all computer users to install software programs regularly. As you know, whenever you install a piece of software, it installs several files and probably Registry entries on the system in order to work efficiently. And this is fine as long as you are using the program, but the problem comes when you opt to uninstall it.

To remove a program in Windows, we normally uninstall it from the Control Panel but quite often this does not completely remove all the entries of the file. Remnants of the old program can remain on your hard drive.

Entries for the old programs can also remain in the Registry, slowing down the performance of your machine. These leftovers may not pose a major threat but they tend to slow down your machine so there is no point of keeping them. There are various methods that you can use to get rid of these leftovers. In this guide, we are going to discuss two of the most commonly used methods that you can also use to completely remove the software leftovers.


Method 1: Manually remove the software leftovers

This method is convenient as it doesn’t involve installations of third-party applications. It is the method you can use to manually clean entries from the Registry. Care should be taken when cleaning entries from the Registry as a small mistake here might adversely affect the functioning of your machine. We are going to use Mozilla as an example in this tutorial.

Step 1: Uninstall the software using Control Panel

To do this, open the Control Panel, double-click on the Add/Remove programs, choose the program you want to uninstall and click on the Uninstall button. This will remove the program.

Step 2: Delete the remaining files and folders

Even though you have successfully uninstalled the program, some fragments of the file may be left in a few of the system folders. To remove them, you’ll need to check the program files and app data. Check the following files for leftovers.

%programfiles%
%appdata%

Just type the above text one at a time in the search box and press enter. It will open the folders directly. If you find any folder with the name of the program you just uninstalled, delete it.

Step 3: Remove software keys from the Windows Registry

You will need to be very careful when performing this procedure. When you uninstall a software program, in most cases, the uninstaller does not remove the program from the Windows Registry. This increases the Windows Registry size. To completely remove the software, you need to remove its key from the Windows Registry. Follow the steps below to remove the program keys.

1. Open the Start menu, type regedit in the search box and press ENTER. It will launch the Registry Editor.

2. Type the following keys one by one:

HKEY_CURRENT_USER\Software
HKEY_LOCAL_MACHINE\SOFTWARE
HKEY_USERS\.DEFAULT\Software

3. Look for a key with the name of the program you just removed. If you find a key, delete it. You can also use CTRL+F to search for such keys.

Note: It’s important to do a backup before deleting anything from the Windows registry so that if something goes wrong, you can restore the system to its earlier state. To do a backup, right click on the key you want to delete and select ‘Export’. It will save a .REG file with the backup of that key.

Step 4: Empty Temp Folder

The final step is to clean the Temp folder. This is the folder that contains all the temporary files and cleaning it is safe. To empty the folder, open the Start menu and type the following commands one by one:

%temp%
temp

This will open the Temp folders. You can now empty them. If the system displays an error message when deleting some files, leave them. The files might be in use by Windows services or some running software.

After following all the steps above, you will be able to completely uninstall a program without leaving a trace on your machine.


Method 2: Use Third-party Software

In such a case, you can always install third-party software to completely remove all the remnants of old software with just one system scan. There are many free and paid uninstaller programs that can get the job done instantly. Below find just a few of the tools you can use.
