Files take extremely long to copy or move over homegroup network (Solved) One of my computers with windows 8 takes extremely long to copy or move files to other computers in the home group. Even small files under 1 MB take several minutes...it is frustrating. It is the only computer in the home group network behaving this way. Please does anyone has a solution to this problem. HELP! I'm using windows firewall and windows defender and it's a fresh windows 8 install running on this computer.
