On Android I have auto update enabled, and it works alright. Sometimes an update removes a feature I liked though, which is more of a problem with the state of software these days than updating.
On Linux I just update whenever I feel like it, or when I need a new feature.
On Windows 10 I never update. I disabled it 3 years ago and will never install another update, ever. They were using automatic updates to reset my privacy changes, pester me with ads, and try to trick me into updating to Windows 11. I'm never on that OS for long enough that it matters. I only use it when there's something that I can't accomplish on my phone or Linux, because some asshole somewhere decided that they're going to force Windows.
