I have been reading about the function keys not working and we are about to go to windows 10. Are we going to have a function key problem on Dells or is this a (other brand problem)?
There millions of users, like me, who have upgraded to Windows 10 and who never reported an FN key problem. There are isolated cases which can be solved. Just insure your computer has the basic requirements for Win10.
I am very happy with Win 10, I used to have Win8 and Win 8.1.
