  2. Everything works fine but this MSE Update KB3140527 - Error 0x80070643 - Windows 10

    Because you did not uninstall MSE prior to upgrading to Windows 10, MSE is unfortunately still installed on your computer.

    MSE is an Anti-Virus program designed for Windows Vista/7.

    In Windows 8.1/10 Windows Defender is the in-built Anti-Virus program.

    Both programs are now conflicting with each other.

    That means you need to uninstall MSE right now.

    After a successful uninstallation of MSE and a reboot, Windows Defender should be automatically enabled and you won't get any MSE-related updates offered anymore.

    So: Please read my prior post, and try to uninstall MSE using the described uninstall-methods.

    Cheers,

    J

    Security Essentials/Defender problem

    On Windows 10 Defender replaced MSE, but didn't remove MSE. A MS tech uninstalled MSE for me with Revo Uninstaller as it refused to be uninstalled by using the regular unistaller. Now there is still an icon on the apps list (but doesn't run when clicked),
    and security settings say they are both running. I guess traces of MSE were left in the registry. How can I be rid of these?

    MSE is not supported on Windows 8 and above.

    Windows Defender have been exactly the same in turns of what they scan and what features they have. Just stick with WD and you'l get the same level of protection.

  5. Having read the OP, they had MSE installed on Windows 7, then upgraded to Windows 10 and the MSE install was kept on there, despite Windows Defender being installed in the OS with Windows 10.

    OP is now not able to uninstall MSE as it is clashing with Windows Defender.

    To the OP - you could try this to see if it works: Microsoft Security Essentials - Uninstall Completely - Windows 7 Help Forums

    MSE wont uninstall

    hmm well in that case its not looking that good according to this thread. You could try booting Windows into safe mode and try remove MSE that way.

    Maybe installing another AV like AVG, might sort things out because 3rd party AV programs usually disable MD and by doing that it might re-enable it when you uninstall AVG.

    Or back your data up and do a refresh - which in essence is a clean install - but yeah *Sad

  14. Already got data backed up, but I am not going to do a clean install as I need to see how many gotchas there are in the upgrade process.

    You Win User
    Can go to %windir%\installer, add the Subject column, and look for MSE, Microsoft Security Essentials, or something like that in the Subject column? If run the installer directly (MSI file), may be able to bypass the message that prevents from uninstalling MSE.
