That is great news. Thanks for the help. As to the updates, I just checked, there is one update, Definition Update for windows Defender-KB2267602 (Definition 1.203.69.0) which failed to install on 22/07/2015. I have also just installed all optionals, but that still shows on Windows Update History as a failed install. As an aside, as I ran updates (I have my PC set to check for and install updates automatically), Upgrade to Windows 10 Home failed to install (Perhaps this is because there is something else that needs to come out for it to install?).
What might be the reason for these failed installs? And the install that shows as failed in the history, will it continue to show as failed even if a later update covering the same code is installed - that is, how do I know if the update was successfully installed at some point? By the way, I don't see anything telling me that any updates are pending, should I if there were an unsuccessful install?
