Every time Microsoft sends out a major update, it screws up the mail app and notification box. Every time!!
MS can’t get their act together or needs to hire employees who know what they’re doing.
DON’T. USE. THEIR. EMAIL.
I have never used MS mail. I have a small privately run service out of Texas that I got 20 years ago, a yahoo account, and a hotmail account (which I hate, BTW).
I don’t EVER log onto my “Microsoft Account” or my “Google Account” because I don’t want them to spy on me and then start receiving spam ads everytime I go online based on where I’ve surfed.
You have to have those accounts for the various services, but you don’t have to be logged onto them unless there is something specific to them that you need to do. Then - log off.
As far as anti-virus services go, I have always used Norton and have never had any problems with it.
Microsoft updates do mess things up with some of my business software. My main business software provider now has a recording on their 1-800 line reminding you that if the print feature in the software is showing an error message (always happens after a major Microsoft update), please run the software manufacturer’s update - at least they are ready for it ...
WIndows 10 ... the bugs are a feature, not a ‘bug’ ...
I've thought for many years that, it's the left leaning corporate culture within the big tech companies that drives down standards of excellence among the staff, and results in substandard, crappy products.
Unless the corporate culture changes, the staff will continue being substandard, and so will the products.
