Choosing between these four full retail Microsoft operating systems comes down to matching the media, license, and PC era to the machine you plan to run. The products are not interchangeable. One is a Windows 10 Home license, two are Windows 8.1 releases, and one is a Windows 98 Second Edition retail box. If you need a modern OS for a current PC, the Windows 10 Home option is the clear anchor. If you are restoring a Windows 98-era machine, the retail box is a different kind of purchase. The right choice depends on the computer you have and the install method you can support.
Quick take
For most shoppers, the Windows 10 Home Full Version is the easiest match for a modern PC: it comes on a flash drive and carries a full Windows 10 Home license. Windows 8.1 buyers have two choices: one titled as a retail license with media and the other as a 2013 release. The Windows 98 SE retail box is the outlier, aimed at someone who specifically wants that era's full retail package.

Product Notes
Windows 8.1 Retail DVD (1 PC/s)
Microsoft's Windows 8.1 retail DVD listing explicitly says '1 PC/s' in the title, which makes the intended install scope clear: one computer, with a retail license and media. It comes on DVD, and the condition is Brand New. The title also carries 'Retail (License + Media)'. Choose this listing if you want a physical Windows 8.1 DVD and the one-PC licensing language right in the title. The limitation is that it is a Windows 8.1 product rather than a Windows 10 product, so it sits one generation behind the Windows 10 Home USB option.
Windows 10 Home Full Version USB 3.0
This is the only Windows 10 product in the group, and it arrives as a USB 3.0 flash drive rather than a disc. The listing says it supports both 32-bit and 64-bit installs, and the condition is Brand New. The listing states a license quantity of 1, which fits a single-PC full retail install. Choose it if you want a current Windows 10 Home license on portable USB media. The limitation is that the listing states a single license, so this is a one-PC purchase, not a multi-device pack.
Windows 8.1 Full Version 2013 DVD
This Windows 8.1 DVD is described as new and sealed, with a 2013 release date in the title and support for both 32-bit and 64-bit installations. It comes on DVD, and the condition is Brand New. Choose it if you want a sealed physical DVD of Windows 8.1 and don't need the '1 PC/s' wording that appears on the other Windows 8.1 listing. The limitation is that the title emphasizes the 2013 vintage and the sealed DVD state, not a one-PC license count, so that exact licensing language is only on the other DVD listing.
Windows 98 Second Edition Retail Box
Microsoft Windows 98 Second Edition is the vintage entry: a full operating system on CD in a retail box, with the condition listed as Very Good. The listing notes the minimum processor speed as 66 MHz and the country of origin as the United States. The listing comes from merchant ZrAV5zknT. Choose this if you specifically want a Windows 98 SE retail-box release for a retro machine or collection. The limitation is that the retail box is described as opened, and the condition is Very Good rather than Brand New, so it is not the new-sealed experience offered by the other listings.
Final Recommendation by Use Case
If you need a modern OS for a working PC, the Windows 10 Home at USD 30.00 is the practical pick. If you prefer Windows 8.1 and want the explicit one-PC licensing language, the Windows 8.1 Retail version at USD 79.99 states that scope in the title. If you want a sealed 2013 Windows 8.1 release, the Windows 8.1 2013 version at USD 55.00 is the option. And if you are specifically looking for Windows 98 SE in a retail box, the Windows 98 SE Retail Box at USD 239.96 is the listing that matches that request.
