I'm hating signing into to Microsoft it's horrible to use!

every single fudging time I am on a work's laptop or my home I am being asked to sign into Microsoft - I can't send a simple email or use app like skype without seemingly having to change my password or wondering what sodding account I'm signed up to - honestly it's horrible and so time wasting and confusing and unintuitive - how annoying can you be Microsoft?!! UGH
