I am not one hopelessly holding on to 7 and all my devices except one are on windows 10.
So the short if I have a HTPC running windows media centre with many add-ons/plugins etc it is also my media storage and basically runs 24/7, past that there is media centre extenders around the house. In short I have a perfectly working home setup and don't want to reinvent it all on windows 10 with different software etc, also I have tried the MCE windows 10 versions/hacks and have some success but not all plugins work and every other update breaks them.
Its not used for browsing the internet as such but does use chrome in kiosk mode for youtube, and occasional browsing for extra content or iplayer etc.
I am thinking just keep going with anti virus software and think about what I am doing if/when online but is there anything else I could/should do to lock it down either on the machine or even at a network/router level.
