My Dell Alienware was upgraded and the Windows 10 Home to Windows 10 Pro Workstation. I replaced a SATA HD, but the Booting drive reset and reinstalled "Windows 11 Enterprise" that is "not activated"?

Hi Microsoft Community,

I bought a Dell Refurbished Alienware Area 51 R7 from Dell in June of 2020. I upgraded the Windows Operating System from Windows 10 Home to Windows 10 Pro Workstation on June 30, 2020. I had a Hard Drive (D Drive SATA) that went out in November of 2023 and my Dell Premium Support sent me, and I replaced the SATA Hard Drive. My C Drive, the SSD and booting drive, reset itself and reinstalled the Windows 10 as Windows 10 Home Operating System. It asked me if I wanted to go to Windows 11 at no cost. I did that, and now I have a "Windows 11 Enterprise" Operating System that is "not activated". I spent 2+ hours on the phone with my Dell Premium Support Technician and he could not change or activate the Operating System (Windows 11 Enterprise). The Dell Premium Support Technician recommended that I call Microsoft Support because Dell doesn't have any Windows Operating System "Product Key". I "verbally" talked with a Microsoft Technician, and she told me to call the Microsoft Store and use my Order Number when I upgraded from Windows 10 Home to Windows 10 Pro Workstations. I want to go back to Windows 10 Pro Workstation Operating System, or upgrade that to Windows 11 Pro Workstation Operating System. I don't have a Windows Operating System "Product Key", which I guess is a "Digital Product Key". I have an Order Number and a Receipt from the Microsoft Store when I upgraded my Operating System from Windows10 Home to Windows 10 Pro Workstation (June 30, 2020). I have gone through the Microsoft Store Support and just get links and recording technicians that don't help me out. I have entered the Installation ID number (9 sections of 7-digit numbers) and the Recording Lady says that didn't work, please call back some other time (&*%$^#). Do you have any recommendations??
