Kind of worried that my updated windows 10 will fail soon... Took a while to actually get it to update. I had to unplug the ethernet cable after it verified the download using the updater or it failed with an error. I only found this solution after a couple of hours searching online because the error code didn't relate to the failure and 'sorry something went wrong' wasn't very helpful either.... My other windows 10 failed the update with 'not enough space' even though there was and had to be installed via dvd.
Now it appears that even if by some miracle it does update it can still bork itself. Genius. Are they actually testing this anymore ? Its more of an alpha - except in alpha developers accept feedback and in the case of microsoft they ignore it.
