I found an easier way to retrieve malware over Tor on Windows, using free open-source software.

Tallow uses Tor and WinDivert to redirect network connections over the Tor network.

After starting Tallow, press the Tor button:

Then you can use wget on Windows:

Onion services can be accessed too:

By default, Tallow only allows TCP connections on port 80 and 443 (Force web-only). Disable this toggle if you need to access other ports.
