Re: In the time it takes to update win-10-nic...
"That is hilarious - while you are of course wrong - Windows Update isn't fast at anything, and the installation requires 32GB of disk space and uses 20GB"
Installation actually requires a recommended minimum of 16GB for 32bit or 20GB for 64bit. Windows 10 itself uses about 10GB on a clean install. The main additional space eaters are page file, hibernation file and of course future Windows updates.
If you have a <= 32GB device then commonly you run out of space for major updates and it's majorly sucky that Windows doesn't have built in intelligence to deal with that.
Hopefully it helps a few people to know that disabling the Hibernation file on such a device will usually free up enough space to update. You can do this from the command line via POWERCFG /hibernate off
