Does setting "DirCache 0" in your torrc resolve the issue?

Yes it look like thats working.

I lost the Guard flag (like expected) but in the last 24 hours i had no problems anymore.

There's a suggested patch on the ticket:
https://trac.torproject.org/projects/tor/ticket/24857#comment:39

But we've had trouble getting people to help with Windows development
and testing.

Can you compile tor from source for Windows?

 

i've never done that before. If there is a step-by-step guide it might be interesting to learn.

Or if we get a fix merged into tor, can you install the Windows
"Tor Expert Bundle" ?

This should be no problem.

I think i will keep the Windows setup at least for some time so if i can help that way feel free to send me or point me to anything Windows related what needs some testing in real world.
