Earlier in the week, Microsoft rolled out cumulative update KB3206309. This brought Windows 10 Creators Update build 14986.1001 to Windows Insiders on the Fast and Slow rings. As we mentioned at the time, details on the patch were sparse. However, while Microsoft is offering nothing official, users are reporting that the release adds improvements to Windows Defender. In post-installation, Windows 10 informs Insiders that it is making improvements to Windows Defender. Indeed, it seems that these improvements are an overhaul of the antivirus package. The revamp brings with it a ‘new look' UI for Windows Defender. “Windows Defender is making some improvements,” the message read. “We're working hard on adding new features and finishing our new look, so not everything is ready quite yet. Some features you're looking for may not be available now, which is why the previous version of Windows Defender is still available on your device.” Aside from giving Windows Defender a lick of paint, build 14986.1001 appears to be focused on security fixes and tidying up the previous build. Microsoft hasn't updated the knowledge base to highlight official changes, so we are just going on word of mouth.
Microsoft Gives Windows Defender a ‘New Look’ through Windows 10 Insider Update
KB3206309 (build 14986.1001) is itself an update of Creators Update preview build 14986 and Windows Defender seems to be the focus of the release. Users report a new UI look for the antivirus program, although Microsoft has yet to confirm the changes.
