The only way to install the Windows 8.1 update is through the Windows Store. Microsoft doesn't offer a support web page where you can download the update as an ISO or an MSI. The Windows Store is your only option. Problem is, my computer could not connect to the Windows Store. I kept getting a message that said:
Unable to connect to the Store. A problem has encountered with the server or a timeout of the network connection. Wait a few minutes and try again.
And that was weird because my computer had no trouble connecting to the Internet in every other case. Every so often, when I tried again to access the store, the Windows 8.1 download page would come up, but the heading text would be placed over the Download button in such a way that I couldn't click it.
Microsoft offers a number of potential fixes for those of you who can't connect to the Windows Store. None of them worked for me, including running WSReset.exe (Windows Store Reset which resets the Store cache). I also tried a number of third-party cleaner tools like RegCure and Windows Store Troubleshooter to no avail.
Windows Store Can't Connect? Here's The Solution:
What solved the problem for me was simply putting ms-windows-store:WindowsUpgrade into the address bar of my browser. It immediately opened up to the Windows 8.1 download page within the Store app with a perfectly clear layout so I could hit the download button without any trouble. Once I got through to that page, I no longer got the Unable to connect to the Store error.
