faulty so got a new win7. Can I use the key of original?  Last
response: in Windows 7  My laptop came with a WIN7 preinstalled
and I have its key on the back of my laptop. However, the hard
disk got faulty and I bought a new WIN7 with new license and
installed it fresh.  So now I have the original key (on back of
laptop) unused. Is there any way that I can use this unused key
while installing a WIN7 on another PC/Laptop? a b D Laptop a b $
Windows 7  You can even change the key on your laptop to it's
original, if it's the same win version. Right click on the
computer symbol on your desktop and go to properties.  If it's
unused, why do you use the key off the new copy of Win7? The OEM
key was suppose to be used with that laptop, but if it's never
been used or activated, it's still a valid key. Related
