Compare that to Arch Linux on 100MBit connection
To update reliably, it requires between 10 seconds daily, 1 minute weekly to about 5 minutes monthly internet access.
(Current machine saw exactly one, 45 kB patch in the past week).
That reminds me how Ubuntu's release upgrader says that an update will take x days on a 56kbps modem (or was it 1Mbps connection, something very slow) as a "relatable" estimation on how long the update will take.
It's worse than that, because updating a Linux system is updating ~every application on your computer, not just the operating system. If you were just updating the core system, it would likely be even faster than that!
On Arch, installing new kernel releases takes like maybe a minute including download time and reloading the kernel modules. At least on my 1 Gbps internet. And I'm not locked out of my own system while it does so. It baffles me how Windows could possibly be so slow.
