MSE vs. Windows Defender
Microsoft confused users over Windows Defender on Win8, with MSE interface and offers viruses definition updates. There is no official confirmation from Microsoft on merge of MSE with Windows Defender. Sine we’re using official windows version, you can go ahead and install MSE but Windows Defender will be turned off automatically, you can’ t start it again with MSE offering protection.
You don’t need to run downloaded MSE with compatibility settings, download , install and update MSE as simple as that.
