I have been unable to use Tor for over a month now. Windows 10 did an update and it has not worked since. I've been looking all over the net for a fix, but I get the same error each time. It gives me a box that says to reset or copy/paste the info and send it to tor, but nothing gets saved. Anyone have an idea why this is?

There is a windows essentials tool for exploring an executable, try googling for that and opening the tor.exe (or whatever tor is called on windows) via it and check what dlls it is requesting and whether they are found or not.

I ran into an issue with Libreoffice the other day that was due to a missing dll thanks to the latest version being compiled with the visual studio 2017 redist which the installer didn't check for while installing. If something similiar happened with tor that might be the cause of your issue. Another possibility is a package you had installed was rolled back as a result of updates. In the latter case, unless it shows up in the dynamic link checking tool, you will be best helped by joining the mailing list and asking there, or filing a bug on the bugtracker.

Do you plan to :
- insert a warning or visual/alert color icon for a suspicious relays ( but how to know that ?)
- the flag of the country (aesthetic improvement ? )
- invite the dev of tor_tools to update their app (is it not first their responsibility ?)
- block the connection if several tabs have the same relays (security improvement ?)
- block Tor if a malfunction ( https / noscript ) happens
- an automatic check tester in case of problem (a command line that i do not know ... i can't open Tor without connection so a bug report is not possible ?)
- alert the user to do not run Tor as root so prevent it by blocking Tor ! (and if i open a terminal as root when Tor runs ; it interferes with Tor ).

you propose a lot of technical improvement at every release : thx.
