You can attempt it when it becomes available on steam. Otherwise the Microsoft Store version is Windows 10 only.
If/when there is a Steam release, you'll likely get a version that can run on Windows 7, but since Microsoft and SEGA both no longer officially support Windows 7 as of January 2020, and the PC version is initially from the MS Store, you'll need Windows 10 if you want to play before that.

Given Microsoft is porting Halo, their flagship franchise, to Windows 7, I find that argument to be quite flimsy.
Also, correct me if I'm wrong, but can't Windows 7 users can still play JP PSO2?
@Zerox9434 Here's the thing, they aren't porting it to Windows 7 directly, they are porting it to Steam, which allows you to install and play it on Windows 7, and the decision to make sure it is working properly on Windows 7 is on the dev, 343. If it was a MS Store exclusive, like PSO2 will be initially, then it wouldn't be able to be installed on Windows 7.
And yes, the JPN version can still run on Windows 7, but SEGA has stated that they will no longer address technical or bug issues that are related specifically to it running on Window's 7 machines, just like when XP support was officially discontinued.
So again, you likely won't be able to play the NA version on Windows 7 until it is released to Steam.
@Zerox9434 For now yes. The question is for how long, maybe a future update could provide Windows 7 users issues with the game. Making it unplayable, the problem with it would be that Sega won't be solving the issues if it only effects Windows 7. But yeah for now Windows 7 users can play the game just fine, and who knows maybe they are able to play it till the end of the game's service.

You do realize that 343 is a division of Xbox Game Studios, which is a division of Microsoft right? 343 isn't some kind of independent studio like Bungie was, 343 IS Microsoft.

You do realize that Steam is a distribution service right?. You can't "port" something to Steam because software doesn't run on Steam, it runs on the OS which Steam also runs on. Unless they are porting it to the Steam OS in which case it wouldn't be running on Windows 7, it would be running on the Steam OS.
More importantly, given that this game was originally on Windows 7 as a .exe rather then a Windows 10 app, that would mean the Windows 10 version is the port and the Windows 7 version is the original version. So why not release the original version before the port?
rather then a Windows 10 app
Most of the time, these are still just EXE Files. The below is where the Windows 10 Twitch App (From the Windows 10 Apps) is stored:
In addition, there's a WindowsApps hidden folder in the Program Files Directory that houses most of the Windows tile apps that have no "Open File Location" context menu:
The example above is the Crunchyroll Windows 10/Store App, The folder cannot be opened by an admin / user. Microsoft's own Process Explorer was used to see this.
@Zerox9434 because the goal was to release it on Xbox before anything else and keep it exclusive to Microsoft for a period of time. Since it has to be downloaded from the Microsoft store, it comes with the prerequisite of having the operating system that Window's store operates on.
Maybe you can find a way to run the Microsoft store from windows 7, so that and you got yourself a game.
