Short Answer: NO There are no legal free ISO disks to download on any version of Windows.
You did not say what brand and model computer you have.
The "Big Name" computers (HP, Compaq, etc.) had OEM Windows installed and that copy belonged to that
computer.
The seller was obligated to give you that copy. But most likely they did not make backup disks and
do not have them.
But you might try
www.restoredisks.com to see if you can buy a set of restore disk for your make and
model.
Other wise, if you can find one, you have to buy a Windows XP CD and use the COA that came with it.
Buyer beware.

| HDD is wiped and it still has the Windows XP home edtion COA number on it so
| i was wonder were i could download an .iso for installing it. One thats free.
