Just a word of warning if you're planning on upgrading to W10. This applies to people using Nvidia graphics cards.
I've been usin W10 insider program for some time now and all was good. However the latest version 10240 is presenting problems which at the moment there is no way of preventing. Microsoft have altered the drivers for Nvidia which create a problem with Photoshop and possibly Lightroom.
With Photoshop the new driver will not allow the photoshop to use the Graphics Processor.
On anothet point I'm unable to use Lightroom as I'm unable to open any catalogue, I'm guessing that this is also due to a similar problem regarding drivers.
As I have W7 on a seperate drive this has not caused me problems. However be warned
