Windows Defender update (KB2267602) fails-error code 0x80070643
What is up? My Dell laptop has been doing nicely since I added W10. Now, the above listed error has occurred The Dell came with W8.1 OS. I updated a month or so ago. I have checked update history and it says 0 updates have been installed, but I got one
last night. It said it would download and restart several times. I got options to reset things based on the new update(s). What is going on?
