Windows enables automatic updates by default, largely to make sure security vulnerabilities are patched even when users do nothing. Do popular Linux distributions take a similar approach? If automatic installation is not enabled, what is the usual way to configure it? I'm mainly interested in security updates rather than feature upgrades, and I'd prefer to avoid unexpected reboots or disruptive changes.

If you want updates installed without manual approval, many distributions support unattended upgrades or an equivalent package. For example, Debian-based systems can use the unattended-upgrades package. The configuration can normally be limited to security updates, while leaving regular feature updates for manual installation.
Most beginner-focused desktop distributions have update checking enabled by default. They’ll usually show a notification or tray icon when updates are available, but wait for you to approve installation. The exact behavior varies by distribution and desktop environment, so there isn’t one universal Linux setting.
A notification-based approach is common because it gives you control over when packages are changed. Updates are generally less intrusive than Windows updates: the system typically tells you if services or the kernel need restarting, and it should not reboot by itself. You can install updates when convenient and reboot only when necessary.
Your choice of distribution and release model matters. A long-term-support release usually receives bug fixes and security patches without constantly moving you to new major software versions. For exact instructions, you’ll need to identify the distribution and version—for example, Debian, Ubuntu, Fedora, or Mint—because their automatic-update tools and defaults differ.
Graphical update tools can often check on a schedule and change their tray icon when updates are available. Some can also install them automatically, but the option and its name depend on the distribution.
