A few hours ago I started with a fresh Windows XP Home install for a computer for my family.
I’m still going. I have lost count of how many times I have had to reboot the machine then get a new round of updates to install. It is ludicrous.
Modern Linux distributions are far superior to this. I recently installed Ubuntu on a several machines; the installer downloaded updates during the install process, so the machine was fully updated, on the first boot.
