On linux, you can do what you wish. You can use a desktop environment with a GUI software center that pops up a notification that prompts you to install updates. Or update by opening the software center and selecting the ones you want. Or use the terminal commands. Or write an alias so you can type “update” and have it execute all your commands in the right order. Or script it to run silently in the background on an automated schedule.
And you can use your computer during updates, there’s no mandatory update during shutdown/boot.
Nah. XP was huge when it came out because NT was so much smoother and more stable than the Windows 9x product line: it was nearly as stable as 2000 with a more modern DE than Windows 95-ME.
But Windows 7 did everything XP did bigger and better. It’s no shocker that all the Windows-like Linux DEs look like forks of Widows 7.
