I installed Windows 8 yesterday (27 October 2012).
Interesting... Microsoft still doesn't seem to understand smooth integration / implementation, and has some serious issues with abandoning accepted standards (POP3!!!!!!!!!!!) but that's another story.
In the App Store, I had six apps that said they had updates available. I selected all of them and selected Install.
Nothing appears to be happening... green dots are flying across the top of the screen, but nothing appears to be updating.
My system date is correct, time is correct, everything else is just fine. I updated an app after first installing Windows 8, and it updated very quickly.
Those apps just don't seem to be updating.
Any ideas? Is the updater bogging down as X number of people attempt to update the same apps at the same time?
I'm on Verizon FIOS and my internet speed is pretty darn good (download speed 77.96 Mbps upload speed 48.52 Mbps from Virginia to test server in Pennsylvania) so I don't think that is the issue.
