    Windows Update Error 0x80070643 for Windows Defender

    Still having issues updating Windows Defender as of 4/3/17, 12:30pm CDT on 10 Pro winver 14393.969 . Windows Update shows Error 0x80070643 but manual update via Defender GUI installed latest virus/spyware definition 1.239.713.0. Re-running Window Update shows everything is up to date.

    It's been at least 4 days since this glitch first appeared on my machines. Any thoughts on why Microsoft is delaying a fix? Perhaps to include in next Patch Tuesday 4/11?
