Microsoft Security Essentials is one of those programs that you just don’t want to delete. This program is bundled with Windows 10 and is used to protect your computer against malware attacks. But there is a problem; both Windows Defender and MSE come preinstalled in Windows 10. So how do you uninstall MSE without uninstalling Windows Defender? Let us show you how to uninstall MSE in Windows 10.
#1 Method: Uninstall MSE via Control Panel
First things first; open up the control panel. You can find the control panel by searching “Control Panel” in the start menu. Here you’ll see all the applications installed on your PC. Click on the application you wish to remove. In our case we will choose MSE. Now press Uninstall button.
#2 Method: Remove MSE via Registry Editor
If you prefer to use a third party tool to remove MSE, then you can try out RegEdit.exe. Open regedit and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Setup\SecurityCenter\DisableFeatures. If present, change DisableFeatures value to 0. Restart your system and check whether MSE is removed successfully.
#3 Method: Use PowerShell Commands
PowerShell commands allow you to perform tasks easily and quickly. One such command is Get-AppxPackage. By running this command, you can list all the apps installed on your device. From the output, you can identify the app you wish to uninstall. Run the following command to uninstall the app.
Yes. If you want to try out MSE, you don’t need to download anything. Simply launch the MSE icon from the Start menu.
MSE starts automatically whenever you log into Windows. However, you can choose whether to start MSE every time you boot up or just once. See How do I turn off automatic startup? for more information.
Microsoft Security Essentials (MSE) is one of those programs you don’t want to uninstall. You might think it’s just another antivirus program, but it’s actually much more than that. In fact, it’s a full-blown security suite that offers protection against malware and spyware. If you’re running Windows 10, however, there’s no way to completely remove MSE. Here’s how to do it anyway.
The Uninstall Procedure Doesn’t Work Properly
If you try to uninstall MSE manually, you’ll find yourself stuck in an endless loop. When you attempt to delete MSE, Windows asks whether you really want to do it. Clicking “Yes,” leads to a confirmation screen where you can choose to keep MSE. After you’ve done that, you’ll see a second confirmation screen asking whether you want to restart your computer. Clicking “No” here doesn’t lead anywhere. Instead, you’ll end up back at the previous screen.
This happens because MSE isn’t installed correctly. To fix the issue, follow these steps:
Users Who Upgraded Without Removing MSE Had Problems Afterwards
Upgrading to Windows 10 is always a hassle. But if you didn’t uninstall MSE beforehand, things could get even worse. Many people reported having issues with their computers following the upgrade. Some couldn’t boot anymore, while others found themselves unable to access certain files.
Microsoft Security Essentials is one of the most popular free anti-virus programs out there. However, it does come with some limitations. For example, it doesn’t allow you to use third party apps like Chrome or Firefox, and it blocks access to certain websites. If you’re tired of dealing with those restrictions, here are three ways to uninstall Microsoft Security Essentials.
Step #1: Click “Turn windows defender off.”
Step #2: Press “OK”.
Step #3: Restart your computer.
Step #4: Locate Microsoft Security Essentials and click “Uninstall”.
To remove MSE completely, open up Windows File Explorer and navigate to the following path: C:\Program Files (x86)\Microsoft Security Client\ Then locate setup.exe and double-click on it. Once the installation starts, browse to the directory where you want to save the files and click OK. When prompted, type in the password and hit Enter. Now, switch to the compatibility tab and ensure that “Run this program in compatibility mode for Windows 7” is checked. Hit Apply and close the window. You’ll see a small progress bar while the uninstallation takes place. Wait till the process completes and restart your PC.
Note: If this doesn’t fix the issue, try method 3.
Microsoft Security Essentials (MSSE) is one of the most popular free antivirus programs out there. However, it doesn’t come without problems, especially when you’re trying to unistall it. If you want to completely uninstall Microsoft Security Essentials, here are three methods you can try.
