Just figured out the solution myself an hour ago, but I have a slightly different set up here. I wanted all my smartphone internet traffic go through my network at home.
Short and simple "route (force) all traffic through hamachi".
For me it was to set "forwarding routes" to "0.0.0.0/0" in Android, but this won't work for your pc I think.
I remembered somewhere I've read it was about to set MTU low or high on the network adapters in windows.
Unfortunately I can't find the thread anymore. I hope this info gave you a better lead to your solution.
