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
STEP 1: Uninstall Software Using Control Panel
First thing first! Uninstall the software using Windows Control Panel.
Windows XP:
Open Control Panel, double-click on "
Add/Remove Programs", select the program name and click on Uninstall button. It'll remove it.
Windows Vista / 7:
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%
%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 Startmenu 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 startmenu 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.
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 startmenu 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.
