Issue: How to uninstall Microsoft Security Essentials?
Hello. Every time I boot my Windows 10 PC I get an error message about Microsoft Security Essentials. I thought that re-installing the program might fix the problem, so I tried doing that. However, I could not do it manually as I do with other programs. Please help as this error is really annoying!
Users typically encounter problems removing Microsoft Security Essentials after they upgrade to Windows 10 from a previous version. Microsoft stated that after upgrading to the newest Windows version, Microsoft Security Essentials should automatically uninstall itself.
Windows 10 sometimes freaks out because, initially, Microsoft Security Essentials and Windows Defender are same tools. Thus, none of them end up working, and users are left with the only option – uninstalling Microsoft Security Essentials themselves.
However, as soon as they try to remove Microsoft Security Essentials by using Add/Remove function in Control Panel, they see that operating system does not allow them to do that. It drops the following error message:
Microsoft Security Essentials Installation Error
You don’t need to install Microsoft Security Essentials.
Error code 0x8004FF6F
Additionally, some users report that they cannot find the application in the list at all.
There might be another reason you are getting problems with Microsoft Security Essentials; mainly, because it is not real program from Microsoft. Recently, a fake security software appeared on world wide web called Microsoft Securoty Essentials.
