Thanks Malc, yes Winaero is great but my problem is not solved. The creators upgrade replaced my AMD drivers with the MS driver which worked, but when I installed the latest AMD driver, Windows reverted back to the previous 1703 version. However it's not a Trainz issue, I will have to look elsewhere.
Thanks
Mick
