No. Not even close.
From the description:
"AS PER EBAY RULES ON OEM SOFTWARE "Original equipment manufacturer (OEM), bundled, or recovery software, is included with the purchase of new computer hardware. It is eBay policy that sellers can't list these types of software unless they are selling it with the original hardware." THE HARDWARE FROM THE ORIGINAL MACHINE IS INCLUDED IN THE SALE.

You are actually buying a decommissioned HP computer, and the associated Windows license.
That license could be deactivated by Microsoft at any time.
Buy a regular license. Yes, it costs more. But Windows costs what it costs.
Would you cheap out on a fake GPU? Or a CPU from Inter? No. The OS is just as much a part of a PC as is the RAM, CPU, Case, whatever.
