Many or most have working serial numbers in the comments associated. Or you can find them on by doing a search. You do not need them to download the files.

ThanksI wave a windows 10 laptop that was given to us, and it is slow as molasses- I mean really bad. I put Linux on it as dual boot option, but even with Linux, its still slow. I doubt that formatting and putting windows 95 or 98 on it will help, but maybe. I do have windows 7 is, but not sure that a windows 10,machine can be “downgraded” using a windows 10 product ID number for windows 7 installation?.
