This windows 7 64 bit version came with a used computer
I purchased years ago - the dealer threw in two original Microsoft
installation disks - 32 bit and 64 bit versions. I've previously posted
an upload of the 32bit version.

As you may know the 32bit version apparently only utilizes
up to 4GB RAM in what it uses for itself and further makes available to your 
applications while the 64bit version does not have that 4GB limitation - 8GB+ 
systems with Windows installed have been commonplace for more than just a few 
years now I believe in any event. I'm also posting a 64bit Windows 10 version 
for you additionally

The ISO file is created using POWERISO 5.5 downloaded from the net
and is bootable of course. Burn the iso file to a blank DVD5 disc using your 
DVD burner drive and thereby create a bootable installation disc. 


When installing skip the product code entry and the on-line
validation, and instead load the Windows 7 activator after installation is completed,
using the start menu to run the loader win 7 activation program from (its in the separate
folder).

While installing windows, you will sometimes/even most often see an annoying 
message from the installation procedure section of the windows operating 
program which says the hard disk you want to install windows on
"cannot be used with windows" (because it is partitioned using 
MBR or GPT - the two variant options in use) when it should
simply say that it needs to switch from one type to the other
depending on what its requiring the partition type to be in order
to proceed.

When this happens, simply access the command prompt from the 
installation screen at the start (shift F10) and then type the following
commands from the command prompt:

diskpart
list disk
select disk 0 (if that;s the right disk number)
clean (that will erase whats on the disk - windows often
wont proceed without the CLEAN command - saying it cannot convert
when you do use this command - which it doesn't tell you to use by the way)
convert MBR (or convert GPT) this is the final command
to convert to whichever type of partition format windows is requiring 
for the particular installation you are doing.
EXIT

If the CLEAN command is inappropriate for you (such as when you 
wish to retain some data on the hard disk, use a program like EASUS
- downloadable from torrent sites additionally) to convert partition
type and to so before installing this copy of windows.

Enjoy
