Thank you for the advice Azath.

Unfortunately i have already pressed the 'Buy' button for Windows 10. It's about the right time to move up a few notches, wipe the drive and build again. I have ISO images of old operating systems all over the place that i tend to believe i need but so far never have.

There are some issues with older software, i am corresponding with some of the companies now, mainly old CAD & Audio applications that i am looking at alternatives for. That's the main bug in the soup now.

Thanks Pat :)
