The disk bloatation in Windows is sky-high. For instance, I don't normally ever run Windows but I bought a cheap laptop, new, with a 30 GB drive, which was an HP Stream intended and marketed expressly for Windows 8, for the sole purpose of running MagicJack to provide me with a VOIP telephone line. Within a month of pressing it into service they crammed the Windows 10 upgrade down my throat and the 30 GB drive ran out of space. Brand new computer obsoleted by Microsoft almost as soon as it came out of the box. No other OS I ever used needed so much disk space for just the basic OS software plus one tiny VOIP application.
Everything is bloated in Windows. My Acer Aspire was a multi-boot job on which I installed FreeBSD and Linux Mint after shrinking the preinstalled Windows 10 partition. It always ran quietly when I booted FreeBSD regardless of whatever desktop or server software I was using. It was a different story, though, when I booted Windows 10, and the cooling fan would start gunning itself like a race car at the starting line. It fought with me to install it's huge, monstrously and obscenely bloated, unattended updates and upgrades. Got angry if I tried to shut it down too quickly, and often put the computer into an unusable state while it gorged itself on the updates. Ubuntu has very similar behavior when it comes to force-feeding you with unwanted unattended upgrades.
Linux Mint is almost as bad about unwanted updates, but at least it provides a way to prevent the update daemon from starting automatically, whereupon it will run almost as quietly as FreeBSD. There might be a way to do the same thing in Ubuntu, but if so I never figured it out. Ubuntu in my opinion is almost as bad as Windows. Out of the handful of systems I've tried, only with FreeBSD or Debian can I control the timing of my upgrades, and only with FreeBSD do I feel confident that I really know what the computer is doing at any given time, or that I'm actually even in control of the hardware that I paid good money to "own." When I run Ubuntu or Windows, I'm never sure who's in charge of the thing, but it obviously isn't me.
Edited to add: Mac OS X also let me control the timing of upgrades-- they also wanted more money for them after a certain point, but that's a separate and unrelated issue, more or less...
