Alright, this has been going on for awhile, and now I'm fed up. Every time I want to update windows, it comes up with this error code - 80090305 Every time I try to update windows defender, it comes up with this error code - 0x80090305 I can't update either! I've looked for solutions online -everywhere- nothing works. I checked what the Microsoft website said, but that didn't help either! I really think I should get these updates, and I'm tired of it popping up and telling me that it can't update. The computer is an Acer (I don't know the exact model, I trying to fix my friends computer and I'll be back there tomorrow.) Anyway, help would be amazing. Thank you! p.s I realize this is my first post, but you know I signed up because I really need help! I've tried everything!
