Hi Basil. My name is***** you for your question and the opportunity to assist.
Do you have a valid 25 character Product Key from a retail version of Windows 7?
This doesn't include a product key from a label on a computer.
In that case you would need to purchase the software.
There are many options and prices.
The only thing I'm not sure about is shipping to the Bahamas.
It depends on the vendor.
Windows 7 has never been a free product. You can download it free from Microsoft but
doing that requires the software license, which is a 25 character retail product key.
There is a lot of free software on the internet, Windows 7 isn't one of them.
It's not that simple. A product key, like DNA and fingerprints, is unique and
is only good for a single installation. Purchasing the software is the only
way to guarantee you get an unused license.
