I have been daily driving a dual booted laptop for the past two years. After a year of distro hopping I settled with fedora + kde and never looked back. I really liked the auto nvidia driver config and it made everything so pleasant to work. Since the last 8 or 9 months I decided to do gaming using bottles and proton ge. I cannot afford to buy games and bottles is a God send at that. Now I realized that I had not logged into my windows partition in over 6 months. So I logged in to check and it told me it needs to download 8 gigs of updates. That sent me into rage and so clean installed everything to be fedora. I have 250 gb of storage locked in limbo because of windows( I have a 512 gb ssd so it was a lot) and today after everything was setup, the os took only around 20gb minus the games. Never felt happier.
Yeah, that’s always puzzled me as well. Part of the reason is that Windows does a lot more than your average Linux distro, and another part is probably that Linux lacks proper antivirus, but even then Windows Update has always seemed weirdly inefficient to me. It seems to be stuck diffing/decompressing on a single core, barely hitting the SSD until it does everything at once.
