You're deciding between two full Microsoft OS packages: a sealed Windows 2000 Professional retail box and a sealed Windows 8.1 Full version DVD. Both are brand-new English-language standard-license copies, so the real question is not which company made them but which package matches the machine you plan to install on. The listed price spread makes the decision concrete: prices run from USD 55.00 for Windows 8.1 to USD 174.97 for Windows 2000 Professional, a gap of USD 119.97.
Quick verdict
For most installs, the Windows 8.1 Full DVD is the more flexible choice because it carries 32 and 64 bit in the title, uses DVD media, and is paired with Microsoft Windows 7 and Windows. The Windows 2000 Professional sealed box is the pick when you specifically want a CD-based full OS from the Windows 2000 generation with a 64 MB minimum RAM requirement.
Price and feature comparison
| Product | Listed price | Price bar | Format | OS pairing |
|---|---|---|---|---|
| Microsoft Windows 2000 Professional Full, sealed box | USD 174.97 | CD | Windows | |

Where each product wins
- Windows 2000 Professional wins when you want a sealed retail-boxed CD edition of Windows 2000 Professional, and the package lists Windows as its OS pairing.
- Windows 8.1 wins when you want a full installer on DVD with explicit 32-bit and 64-bit support and a pairing of Microsoft Windows 7 and Windows.
Product notes
Microsoft Windows 2000 Professional Full (Sealed Box)
The strongest reason to choose this copy is the concrete package: a factory-sealed retail box, a full OS, CD media, and Windows as the indicated OS pairing. It also includes a 64 MB minimum RAM requirement, which fits the older hardware generation implied by the product name. If you are restoring a Windows 2000-era machine or want a sealed full copy rather than an upgrade, this product matches the brief. The trade-off is less flexible media and pairing: CD only, Windows only, with no 32/64-bit language in the title. That makes it a narrower fit if the machine in front of you runs on DVD-era Windows 8.1.
Microsoft Windows 8.1 Full Version 32/64-bit DVD
The decision point here is the 32 and 64 Bit claim in the title plus the DVD format. The package is a full version from 2013, and the OS pairing is Microsoft Windows 7 and Windows, so it is a more clearly multi-platform installer for a 2013-generation machine. If you want to keep a single full OS DVD around for both 32-bit and 64-bit installs, this is the one that states that capability. The limitation is its era: this is a Windows 8.1 release from 2013, not a later Windows edition. It also uses DVD rather than CD, so it will not help a CD-only Windows 2000-era setup.
Final choice by use case
If you are after a sealed, full Windows 2000 Professional retail box on CD, choose that product. If you want a full Windows 8.1 installer on DVD with explicit 32/64-bit media and a Windows 7/Windows pairing, choose Windows 8.1 Full. Match the OS generation to the machine you are actually installing on, and the better pick becomes obvious.
