well, I bit the bullet and have updated the laptop (W7) to windows 10 - so far so good it took several hours to go through the whole process. I selected custom install and told it I would decide which apps would use for pics, videos etc. the first thing I tried when it was finished was to get on the net, visit here, kick up photoshop/indesign/bridge etc, do some web mail - all of those programs work just fine. So, hoping there are no issues in the next few days, then I can decide whether I want to upgrade the main PC (W8.1)
