Well, I don't see how TP-Link could fix a Windows issue, but if it bothers you that Windows has named your wired connection after a wireless network that it was once connected to, then you could just remove the corresponding key from the Windows Registry using regedit.
Caution! In case you are going to do that be sure you are doing it very carefully. After confirming with "Yes" the changes are immediately being saved.
Windows keeps a list of all networks it has ever been connected to under
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
You have to click through every profile {.......} listed under there until you find the one that contains a "ProfileName" with the value "Guest_2".
After the correct profile has been deleted (you can also first make a backup of it via right-click -> Export) just re-plug the Ethernet cable and then Windows should name that connection "Network" or whatever the word for "network" is in the language your Windows uses. In case that laptop computer has been connected to other wired networks previously, then the name could also end up to be "Network 2", "Network 3" and so on. That name, however, could also be changed by editing the value of "ProfileName".
Keep in mind that if your AX72 still broadcasts a wireless network named "Guest_2" and you re-connect your laptop to that Guest_2 wireless network, then Windows would likely rename your wired connection again. (I am pretty sure in Microsoft's view this is intentional, and not a bug)
