How to Remove Leftover Files After Uninstalling a Program on Windows 10

As we know, uninstalling a program on Windows does not clear their accompanying files off your hard disk. Over time, these leftover files will eat up the drive space or cause the unexpected effect. In this article, I’ll take you a through step by step guide on removing leftover files after uninstalling software on windows 10. I’ll also give a few aids through which you can dispose of those files on your PC.

The Cleanup Process

As I said earlier, there are two significant ways to clear these files on your PC. You can do it manually from the control panel. As the name implies, this involves a manual step by step process.

Method 1: Manual Cleanup Using Control Panel

Step 1: Use Control Panel to uninstall any Program of your choice

  • Go to the search box of windows 10 on your PC and type the control panel in the search box and then click the app of your choice from the search result.
  • Go to programs (they should be arranged by category)> Programs and Features.

Step 2: Delete the Remaining Files and Folders

At this stage, you already got the program off your PC — not quite. You only uninstalled the program, but unlike the actual employee, this program does not take its stuff along. So the best step is to clear your PC if any leftover files from the program. What you need to do is to check your program files and app data. Check folders like %programfiles% and %appdata%.

  • Put these folder names in your search bar, and press enter to open them.
  • As you go through those folders, check for ones that have the name of the program you just uninstalled. Once you see these folders with the title, delete them immediately.77

Step 3: Remove App Keys from Windows Registry

Another place you need to visit is the windows registry. More often than not, the program does not wipe from the windows registry when you uninstall it. You have to go back to the registry to take it out.

You however need to take some caution here. It’s advisable to back up your registry just in case a mistake occurs. In most cases, uninstalling a program doesn’t remove the program from the Windows Registry, which could increase the size of the Registry. So, you should delete the Registry keys.

  • Open your registry pressing win+R. Type in registry and press ok.
  • Check for the following keys: HKEY_LOCAL_MACHINESOFTWARE, HKEY_CURRENT_USERSoftware, HKEY_USERS.DEFAULTSoftware.

3. If you find the key that bears the name of the uninstalled program, delete it.

Step 4: Empty Temp Folder

This is the last step of the process. It is especially advisable to clear out the Temp folder that contains all the temporary files. This is a safe process for the mental health of your PC. These are the steps to take:

  • Go to your search bar and search for %temp% and temp one by one in the search bar of Windows 10.
  • Clean out temporary files.

Right now, after finishing the above four steps, you can effectively remove leftover files after uninstall.
