I ended up disabling a handful of services altogether to prevent it from doing this. Windows Media Player especially was a huge culprit when it came to trying to share stuff it wasn't supposed to.
To disable them pull up the services by searching for services.msc and running it as admin, or hit ctrl-alt-del and under the services tab there will be a "Services..." button to do the same. For some reason the the latter was the only way I could get mine open right now, but usually either way should work.
Once it's up look for and disable the following services:
Media Center Expander Service
Net.Tcp Port Sharing Service
Routing and Remote Access
Windows Media Player Network Sharing Service
Windows Remote Management (WS-Management)
After that just reboot and you should be good to go.
3What do you mean by "accessible?" How are you accessing your system from others? – ernie – 2013-09-10T23:44:33.140
