It’s a Dell Inspiron laptop, at least 15 years old.
Is there a adapter or an external hard drive enclosure I can use? The one's I found in Amazon seems to have a different set of pins:

It's a laptop HDD – as people writing their answers via comments mention, those very often had an adapter from regular 44-pin laptop IDE to the laptop manufacturer's proprietary "easier to plug" port stuck on them. You can carefully remove the adapter, by which I mean very carefully peel it off from both ends at the same time, as those pins will bend sideways if you try to tilt it off from just one end. (Which is one of the reasons they had those adapters, really.)
Once you do that, you'll have a regular 44-pin "laptop IDE" connector (physically smaller than desktop 40-pin ports).
There are plenty of USB adapters for this (often with the larger desktop IDE on one side, smaller laptop IDE on the other).
While a 15-year-old HDD should be working perfectly fine, it's probably a better idea to image the disk first (using Disk2vhd or whatever), then extract files out of the image – mainly to avoid the "Give access to this folder?" Windows prompts that would otherwise cause a lot of writes back to the HDD, and as a general precaution in case the HDD happens to be on its last spin.
On Linux I'd suggest having ddrescue installed so that you could make a 1:1 copy of the disk if it's having difficulties reading some parts. (I don't know if it's available for Windows, but the raw image it creates can be later turned into a .VHD for browsing in Windows.)
