Yeah and that's a problem!! My 1511 version of Win 10 started updating yesterday morning on my new 4G metered service and I was thinking I could take the 5GB download hit on my monthly allowance. Ask me how that worked out?
It now only downloaded 16.07, but it also downloaded 1703 and BOTH failed to install because the 40GB partition on an 80GB hard drive that it was installed on RAN OUT OF ROOM after it downloaded 10GB of updates that weren't installed. Before I started the
upgrade there was over 15GB free space?? And not only that, but I moved the partition out enough to do the install and what did it do then? It installed Update Agent then proceeded to DOWNLOAD THE UPDATE AGAIN??
So here I am again with 15GB of downloaded upgrades to do what less than 5GB was suppose to do to begin with. And never mind what all this extra data is going to cost me over what I'm already paying?????
Wish I'd never, ever seen Windows 10 because it's the biggest screwup I've ever seen in my life!!
