Hi. With Win10 I've noticed that left-clicking the volume icon at bottom right no longer works. Neither does the network icon. These icons worked right after install, but now randomly appear to just stop working. Other icons (program icons, for eg) next to them DO work, and right-click works, just not left-click. I can adjust the volume with the slider on the keyboard but not the mouse any more. I also have issues with the keyboard randomly stopping working, but this sometimes happened with Win7 and could be because it's old

This is just one of a bunch of issues Win7 never had and Win10 does have. I'm thinking this is why they released it free
