Usually logging into Reddit shouldn't be a problem. Maybe try reloading the connection. I really don't know that many "Tor-friendly forums". Either way, what I may recommend to solve your problem would be to either use one of the USB headers found on your Motherboard via an Adapter (like this one: http://amzn.eu/auOJwpl) or partitioning your HDD with GParted so you may use it to store your Windows-Installer on it, which you may optain from here: https://www.microsoft.com/de-de/software-download/windows7 Sadly Windows 10 has no official .iso files out there, only a Tool to download them for Windows.
Be warned though. Do this wrong and you could loose your openSUSE installation as well.
Otherwise, if you have access, you could always use a secondary PC to put the .iso on a small HDD (small HDD may be optained for almost free via Ebay, etc) and go that route.
Furthermore, I'm affraid to ask what lead to a situation where your PC lacks USB. Did you perhaps try to harden your Notebook?
Have a nice day,
