windows defender definition update failed

I’m not a “Windows” person, so I usually keep my mouth shut about things that only marginally enter my work, that I don’t care about, and that I never admit any knowledge abou – but I think there is something worth mentioning. Maybe microsoft had some kind of “reset” in mind with the windows update, I don’t know what criteria they were using to decide which files had to go, but to do it without the consent of the users or administrators is seriously bad. And that’s fine if that’s their desired policy, but there will obviously be data loss for many applications. Some administrators might choose to delete/re-init data from Local and Roaming in order to reset user profiles every time they log in because they want user sessions to remain stateless. You can’t just delete this willy nilly and not expect lots of things to break. On my computer there’s everything from game files, webcam settings, SSL certificates, etc. It’s debatable whether MS has a responsibility to care when third party devs misuse things.ĮDIT: (admittedly, MS’s own Outlook has always used it for massive. To be fair, %LOCALAPPDATA% is supposed to be ephemeral and non-persistent.
