WINDOWS 7 HOME PREMIUM 64 BIT OPERATING SYSTEM .

Microsoft windows 7 home premium operating system. 64 bit, brand new never been used. Bought by mistake as we needed 32 bit. The packaging has been opened but the program was not installed and the license key has not been used. Product states designed to install on new computer but will upgrade previouse versions of windows, as the 32 bit version did to our computer when we finally bought the correct one Happy to post at buyers expense.
