Hi there and welcome
What was the make and model of the Laptop?
ok, all HP computers come with windows else the computer would not do anything at all.
What is it your actually having the issue with? What are you trying to do that you cannot?
ok, you need Microsoft Office not windows for this.
This you can purchase from my link below.
Windows is what runs your computer and this you already have. It is Office you require to open Excel documents and that you purchase from the link I gave you
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
