3 Ways to Remove Residual Files After Uninstalling Software on Windows 

The first step to free up space, and get rid of apps on Windows is to uninstall them. But, it is worth noting that uninstalling programs does not remove all traces of it. App data, cache, registry data, etc. can be left behind. To help you, we have listed three methods to remove residual files after uninstalling software on Windows.

Remove residual files after uninstalling software

All of these methods are simple and help you free up significant space, especially if you have never bothered to delete these software files before. Additionally, we have also added a method that helps you completely uninstall a program at once. Let’s get started.

1. Delete Registry Keys

Registry keys are a database of information, critical for the program’s functionality. The registry key of an application involves all the configuration and installation data – such as your product key, custom install settings, etc. Deleting the registry keys for an uninstalled app removes its leftover traces.

However, you need to be careful as you proceed to remove the registry keys. Ensure you exactly know the uninstalled app whose keys you need to remove, especially in cases where you have multiple versions of the same app installed.

To prevent any mishaps, we recommend backing up a copy of the registry keys if you ever delete an app essential for your PC to function properly.

Step 1: Open the Registry Editor app from the Start menu.

Open Registry Editor

Now, the Registry Editor will have the list of all programs – even the uninstalled ones. Observe any folder of an uninstalled app. In our case, we uninstalled Mozilla Firefox, and yet we see a folder here.

Step 2: Right-click on the folder of the uninstalled app.

Step 3: Now, click on Delete.

Step 4: Click on Yes to confirm key delete.

Apart from the registry keys, apps also leave cache and other non-important data behind despite uninstalling them. These useless files are often kept in the temporary folder on Windows. Let’s see how to delete those in the next section.

2. Delete Temporary Folder

While there are multiple ways to delete temporary files on Windows, we will show you the easiest one to remove the leftovers of the deleted application. You will be surprised to see how many of these folders are present.

Step 1: Open Run from the start menu.

Open Run

Step 2: Type in ‘%temp%’ and hit OK.

Type the code for temp files

Step 3: This will open up the temporary folder. Use Ctrl + A to select all the files.

Step 4: Now, right-click and select the delete option. They will now be moved to the recycle bin.

This is all you need to do to remove the temporary files. But, if you want to go a step further as you remove residual files after uninstalling software, you can take a look at Windows Disk Clean up too.

3. Use the Disk Clean-up Tool

The Disk Clean-up tool is an easy one-click tool to delete any unwanted files left over on your system. Here’s a step-by-step procedure for the same.

Step 1: Open up the Disk Clean-up app from the Start menu.

Open Disk Cleanup

Step 2: Select the drive and click on OK.

Click OK for C drive

Step 3: Check the box for Temporary files in the Disk Clean-up window. Now, click on OK.

Do not manually check any other box other than the one mentioned, as whatever has to be cleaned up will be automatically selected by Windows.

Step 4: Wait for the Disk Clean-up to delete the unwanted files.

Alternatively, you can also opt to clean up system files to remove more such unwanted files. Here’s how:

Step 1: Launch Disk Clean-up and select ’Clean up system files’.

Step 2: Select the drive and click on OK.

Click on OK

Step 3: Wait for all the files to be removed.

Using the above methods, you can clear all the residual files after uninstalling software on Windows. But, what if there was a method to uninstall the app and remove all traces of it at once?
