Nothing to do with SQL Server for once. Was having problems with my Dell Latitude 10 Windows tablet. Decided to reset the Windows 10 installation. Used the option in the control panel to reset to original installation. Now what that actually means is as it was when the tablet was shipped – Windows 8. So I then had apply updates, upgrade to Windows 8.1. Apply updates, upgrade to Windows 10. Except couldn’t get the Windows 10 option to appear. After a quick search I found Get Windows 10. Would have been a much easier and faster to way to do a fresh install.
