Windows Update Error 0x80070643 for Windows Defender

For those who have been experiencing the Windows Defender update error 0x80070643 recently, please check my latest update to the thread On Windows Defender Definition Update error 0x80070643.

All seems to be back to normal for me as of this morning. tried initiating an update three times over the course of the past hour, all requests were processed with no errors.

Yay! It seems fixed. :)

Tested latest update(s) and all appears to be working as it should. Thanks to Jason Yim and the WD Team. Marking this as solved.
