I spent about four hours last night and another hour this morning trying to upgrade, with no success. I hate this thing.
- I had Windows 8, which doesn't have the 'get Windows 10' icon. I had tried to upgrade to 8.1 several times in the past but always got an error message (after about 2 hours).
- Found out this was because I'm dual booting Windows and OS X. Unplugged the OS X HD and finally got the Windows 8.1 upgrade direct from the Microsoft app store.
- Still no Windows 10 icon. Check for Windows 8.1 updates but there are none.
- I download the standalone updater. It churns away for a while and the progress bar starts to move. Stalls 90 minutes later at about 30% and has to be killed in the Task Manager.
- Try it again. This time it hits 45% before dying.
- Check for Windows updates. Now there are 127 Windows 8.1 updates available. I install them all, then some more pop up and I install those too.
- Finally the Windows 10 icon appears, so I reserve a copy.
- Restart, but the Windows 10 icon is gone. Apparently it should still be there. The .exe associated with it doesn't do anything. The standalone updater now quits with an error message.
- Force Windows updater to start downloading the files via a command prompt. Hangs at 27% and gives an error message.
- Check for updates again but Windows updater is dead. It has an error code which I look up on the Microsoft site. This leads to an obscure tool specifically for fixing the Windows updater, which successfully brings it back to life.
-Restart the updater. Hangs at 50%...
GRRRAAAHHH! This is the worst user experience I've ever had in any piece of software. I've updated OS X countless times with no problems, but it's taken me more than a year just to get from Windows 8 to 8.1.
This must be why they allow 12 months to claim my free Windows 10 upgrade.
