Downloading WoW3.3.5

Hi guys first i want to say sorry for my bad english

I am looking for downloading wow 3.3.5 without waiting 24 hours.. because my internet download speed is 310kb/s.. it takes lot of time... is there any way to play wow 3.3.5 while downloading in background like cata/mop? or another easy way?

I don't have utorrent... i am downloading with mega co nz
I can't install programs in my pc because i forgot my administrator password for win 8 it always asking for pw when installing programs..
