New computer - to do list/task list

[dizzycooks]

DH bought me a new computer yesterday.  It's beautiful and I'm excited, but I haven't had a computer in about 2 years.  This one has Windows 10 so it looks completely different than anything I've used previously.  I had a MacBook at work and that was lovely, but this seems different.  I need some where to create lists and manage my tasks and calendar.  What do you recommend?
