There is steamcmd - I don't know if it works with games in general or only servers:

引用自 Acetyl：

Last client version to support Windows 7 is now unable to handle steam's latest compression scheme, giving "corrupt download" errors. This bricks your games if you leave offline mode and it detects an update. Clearing cache and relaunching in offline mode resolves it, however it is not ideal. An external commandline tool should exist to download or patch games, independent of chromium webapp nonsense.

Win 7 is no longer supported nor has been for a while.

Dual boot or install a primary compatible OS.

Hmm. Seems promising. Looking into this now.

windows 7 is long dead, time to upgrade or be left behind.

Then your games won't work.

All these nay sayers. You can continue using Windows 7 with SteamCMD as pointed out.
It allows you to download and update games to maintain your current Steam library.

If you want I can walk you through it.

SteamCMD is working so far (just updated SOMA), though the existing documentation is not great.

I would say first:
-Don't put steamcmd in the root steam dir (with steam.exe etc). It will overwrite steam, then when steam launches it will update itself and overwrite steamcmd. Put it in another / a subdir (I made a directory _steamcmd).

-Set "force_install_dir" before logging in. When it says "target directory" it means to point to the "steamapps" directory install root. So if you pointed it to eg "C:\Games\Steam\steamapps\common" it would make a subdirectory there "steamapps\common\<gamename>" and not work properly.
If you're using the default location and put a subdir there, the location would be "..\"

I haven't tried making a batch script yet to do all the logging in and out for different install drives yet, and have it loop through every appmanifest_<appID>.acf to pull the appids automatically.

Also you have to use the default windows cmd terminal. eg MSYS2's mintty doesn't print its output correctly. Also the program ignores breaking with ctrl+c until it's done doing whatever it's doing.
