Surely there is a lot of difference when you upgrade to a software you actually use to produce something, like PS or PTE. The incentive is new tools, better ways of doing things and sometimes ways that change your workflow and even your ability to create images more effectively. I am thinking of how PS now deals with contrast and PTE animation
An OP doesn't have any impact at all, unless they claim its much faster, which they always do anyway. There is always some risk when updating Windows. So, when you only use W7 just to run PTE, I am interested to know what Jeb felt he would gain. He could have said that he realises there is no measurable gain, but wanted to see what W10 was like while it was free, but he started to worry about life being short.
I recently did much the same thing and broke my own ideas of only upgrading when a new computer was built, but W10 said my laptop was compatible and it was free. I had a bit of time on my hands and decided to take a look because I felt i could not ignore it forever.
it installed OK, but after a few days i realised no graphics card software had been installed and that impacts my ability to use the laptop to demo photoshop. Some things will not run. Sadly, the laptop, which doesnt seem really old to me is not destined to have drivers written for one of the two cards in the laptop.
The upshot is I either live with the upgrade and genetic drivers for the ATI Radeon cards, but that prevents the laptop from being used for the main purpose is was originally bought, or return to Windows 7
So, back to Jebs question and mine. When your only using W7 to drive PTE on a Mac, where is the gain, apart from curiosity.
