Did you choose the option to "Keep my files" or similar? To be honest, I am not sure what this 'reset' does, but I suspect that it isn't a complete new installation of Windows, in which case it won't really get much better.
As another user mentioned, the easiest way is to download Windows 10 from Microsoft. This also gives you the option to create a bootable USB stick from which to install Windows. It even guides you through the process.
That said, there is currently an SSD on a great deal, 120GB for £24. This would make a massive difference, believe me. You would need a few fittings, probably just a bracket, but the place selling this even provide a video showing you how to do it! This is also non-destructive, so your existing hard disk is left intact.
If you lived near me, I would happily do it for you.
This is interesting. If, for any reason, my computer suffers a similar problem does this mean that I can download W10 from MIcrosoft at no charge? The idea of having a bootable USB stick in case of a problem appeals to me.
Then there is the problem of a Windows installation having to be registered to a particular computer, or so I thought.
