I had a minor issue where my wireless would not connect ,turned out it was my hidden SSD,there is a box you must tick if you have a hidden SSD so it can connect,don't think that is your issue because you say yours is a driver issue.
As to shutdown ,reboot etc what's wrong with right clicking in left corner like this
I'm not sure what a "hidden SSD" is, but I *do* have what I would call a "dormant SSD" -- my Intel 520 is currently on a SATA port which is disabled in BIOS. I suppose there might be a way Win8.1 knows it's there? So, can you elaborate where that box is that should be ticked for a hidden SSD?
Nothing "wrong" with clicking in the left corner, but why not have a single click do the same. I realize I mis-described my shortcut, as it's not on my desktop, it's on the task bar -- always visible and with a single click can shutdown or restart. I just wondered outloud why shutdown.exe with the /r switch doesn't work in Win8.1 any more.
