How to Completely Uninstall / Remove a Software Program in Windows without using 3rd Party Software?
Generally all computer users install various software programs regularly. Sometimes they keep them and sometimes they decide to remove them.
To remove a program in Windows, we uninstall it from Control Panel but many times the default uninstallation utility provided by the program doesn’t remove the program completely. It lefts some entries in Windows Registry, some files in various folders in your hard disk drives.
These leftovers might slow down your system and there is no point to keep them in your system.

There are many 3rd party software like Revo uninstaller, etc are available on Internet which claim to completely uninstall a software program in Windows but sometimes these software also fail to completely uninstall a software from your system.
We here at AskVG always try to do the things ourselves so today in this tutorial, we are going to share some easy to use steps which will help you in completely uninstall a software program in Windows.
So without wasting time lets start the tutorial. We have taken Mozilla Firefox as an example in this tutorial:
We have divided this tutorial in 4 steps:
- Uninstall Using Control Panel
- Delete Remaining Files and Folders of the Program
- Remove Software Keys from Windows Registry
- Empty Temp Folder
Table of Contents
STEP 1: Uninstall Software Using Control Panel
First thing first! Uninstall the software using Windows Control Panel.
Windows XP and earlier:
Open Control Panel, double-click on “Add/Remove Programs“, select the program name and click on Uninstall button. It’ll remove it.

Windows Vista and later:
Open Control Panel, click on “Programs and Features“, select the program name and click on Uninstall button.
STEP 2: Delete Remaining Files and Folders of the Program
Even though you have uninstalled the software using Control Panel, some files of this program might still remain in a few system folders.
To delete these leftovers, you’ll need check following folders:
%programfiles%
%programfiles(x86)%
%appdata%
If you find any folder with the name of the software program which you uninstalled using 1st step, delete it.
NOTE: You just need to type the above mentioned text in RUN or Start Menu search box and press Enter. It’ll open the folders directly.
Program Files folder:
Application Data folder:
NOTE 2: 64-bit system users will also need to check “C:\Program Files (x86)” folder. Here we assume your Windows is installed in C: drive. If you installed Windows in any other drive, replace C: with that drive letter.
STEP 3: Remove Software Keys from Windows Registry
You’ll have to be very careful while following this step. Follow this step only if you are comfortable with Windows Registry and if you have used Registry Editor in past.
When you uninstall a software program, many times its entry in Windows Registry is not deleted by the uninstaller. It might increase Windows Registry size.
To completely uninstall the software, you’ll also need to delete its key from Windows Registry.
1. Type regedit in RUN or Start Menu search box and press Enter. It’ll open Registry Editor.
2. Now go to following keys one by one:
HKEY_CURRENT_USER\Software
HKEY_LOCAL_MACHINE\SOFTWARE
HKEY_USERS\.DEFAULT\Software
64-bit system users will also need to check following extra key:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node
Once you go to the above mentioned keys, look for a key with the name of your uninstalled software. If you find a key, delete it.
If you get an error while deleting a Registry key such as “Cannot delete key: Error while deleting key“, you’ll need to take ownership of the key as mentioned in following tutorial:
[Guide] How to Take Ownership (Permission) of a Registry Key in Windows?
Sometimes the key name might be based on the company name or developer name so if you suspect a key, expand it and check whether its related to the uninstalled software program. If yes, you can delete it.
PS: Make sure to take a backup before deleting anything from Windows Registry so that you can restore it later if something goes wrong. To take backup, right-click on the key which you are going to delete and select “Export“. It’ll save a .REG file containing the backup of that key.
PS2: Expert users can also find all occurrence of the key with the name of uninstalled software using “Ctrl+F” and delete them. You’ll have to be very cautious for it. Delete the key only if you are absolutely sure that the key was created by the uninstalled software.
STEP 4: Empty Temp Folder
At last you can also empty Temp folder which contains temporary files and cleaning this folder is absolutely safe.
To empty Temp folder, type following one by one in RUN or Start Menu search box and press Enter:
%temp%
temp
It’ll open Temp folders. You can empty them. If Windows shows errors while deleting a few files, leave them. These files might be used by some running software or Windows services.
That’s it. After following the above mentioned steps, you’ll be able to completely uninstall and remove a software program from Windows.
If you have any question or suggestion, feel free to post them in your comment…

Hi, VG, I am trying to reinstall software that is malfunctioning and going into the wrong page when I open it up after I’ve used uninstall in the control panel, then used my search in explorer and cleared those out and manually going into the actual program directory and registry and cleared out by the known software and registry name of the program. Then I rebooted by PC and reinstalled the software from my thumb drive and the same results. I took the same thumb drive and installed it on my father’s laptop and it runs beautifully. I am running Win 64x and dad has 10. Is it possible that I am missing an operational file or for sure I am not clearing out the registry completely. How do you clear the registry when the files are not associated with the name? I would appreciate any suggestions you could give to get my program running right.
Paul.
^^ You can also try to clean temp files and registry using CCleaner:

^^ You can end task of the file using Task Manager.
Hi,
I tried the steps which you have provided to clear the registry of an application and re-installed it. But, still I get same error message saying ‘Your trial version has expired’ when I open the application. Please help me in this matter.
^^ Some software programs create extra system files or registry keys which are not deleted when you uninstall the program. It’s done so that the software can detect whether you have already used the trial version.
thank u so very much
