Spyware or malware or adware. The beyond-obnoxious badgering to log in, log in, LOG IN!!! with your "Microsoft account" to do ANYTHING renders the OS totally unacceptable in my house... and I regret replacing my parents' computers with new Windows machines plagued with that offensive behavior, along with crippling UI defects (some MS apps ignore the system-wide font-size setting, for example) and missing fundamental applications (like a competent E-mail program).

I was a software developer of large Windows-based systems for over a decade, before going to work for Apple. I regarded Windows as a sharp knife, and Mac OS as a child's safety scissors. Today, Windows is a depressing, hopeless mess and Mac OS is what I rely on daily to get stuff done. I hope rumors of Apple introducing touchscreen Macs are wrong. Doing so would require degrading the OS UI for a stupid, failed idea... leaving no good mainstream desktop OS.
