by default nothing is proxied and the user interface requires individual applications to be selected for proxy. as Kyle mentioned this is insufficient protection for Tor users since various Windows services may access network resources outside application proxy settings. if WideCap were to default all applications proxied that would be more useful. > ...

I set mine to 100. there are actually two issues (or more?) for non-server Windows running Tor. the usual problem Tor encounters is not related to the number of concurrent attempts but to kernel non-paged memory resources consumed to exhaustion when lots of active non-overlapped-I/O sockets are in use. details here: https://wiki.torproject.org/noreply/TheOnionRouter/WindowsBufferProblems the concurrent connection attempt limit is easier to fix, although messing with system files is generally not advised! best regards,
