As it may seem, Microsoft is more concerned with the security of the Windows 10 end-user. The latest version of the operating system preview was released with a significant improvement in this area.
The new Windows 10 Redstone build 14271 comes with Windows Defender offline enabled, a feature that allows users to scan for threats before logging into Windows.
A boot scanner is definitely a feature that all modern solutions should have antivirus, as it could prevent malware from running and loading at startup.
Windows Defender Offline is not a new feature, as Microsoft has first released 2011.
It was available as a standalone application that allowed users to scan their computers at boot time. The latest update released 2015, and since then, Microsoft has reported nothing about this functionality and Windows 10.
However, Windows Defender Offline is now integrated into Windows 10 and is available through the settings screen. The same feature was available in the new OS from build 1511 but was not included in the Settings screen, and the only way to start it was through the Powershell MpWDOScan command.
It should be noted that build 14271 is only available to those registered in the Fast Ring of the proletterof Windows Insider. Naturally the new feature will be available to everyone when Redstone launches this summer.
