Windows 7: Is it safe to Burn an exact copy of Windows 7 Installation Disc

Is it safe to burn a Windows 7 installation ISO image using the 'exact copy' option, meaning making an exact duplicate from an already existing CD. Or is it safer to burn a CD from the original ISO file? Wouldn't the 'exact copy' option have higher chances for data corruption, especially since it is a boot/installation CD?

I'm not sure of your questions. The official .iso file is an exact copy of the disc in file form. Whether you copy the original disc or make a disc from the original .iso file, you should end up with the same thing. I'd probably opt for the .iso file, because the burn would go faster, but that's the only difference.

Ok thanks, that's exactly what I was asking.

When I created the .iso copy of Windows 7 am I violating the EULA agreement?

If my system crashes completely and I have to reload Windows 7 using the .iso copy, will it accept the same product id or do I need to purchase a license?

Your disk/iso is not unique, your key is. You can reinstall windows and use the same key.
