hi. got windows 8.1 64 bit enterprise on a windows toshiba satellite pro laptop. and using a screen reader jaws for windows from Freedom Scientific Home Page. second time had to install windows 8.1, the first time was messing around and got locked out, and had to have sighted help from my parents, to restore my windows 7 64 bit pro, on dvds i had created for backup. so did do the registry hack, but did not work. so, is there a software package, that will install or enable the shutdown and wake up sound, for windows 8.1 i had for windows 7. can any one suggest any thing, do not really want to mess around with the registry if possible. got my machine set up the way i want. thanks. marvin from adelaide, australia.
