Am a happy W8.1 user and am reasonably careful security wise.
However, many web authors say you should use the latest version of windows to ensure you have the best security.
Should I move to W10 and all its problems we read about or is W8.1 still safe enough ?
( I did try out W10 with the free upgrade last year but I kept having freeze ups so reverted to 8.1.
However did take system images of W10 so should be able to go back to it, this time trying a clean install to see if that cures the freezing )
