Windows 10 Security Update breaks TSVN Auth?

Hi!

Are there any TSVN users out there that have ran into trouble using TSVN during the last couple of weeks since installing Windows 10 Security Update KB3193494 or KB3189866?

The scenario is that installing any of these updates seems to break TSVN authentication.
Trying to checkout or update results in "Error running context: An error occurred during authentication", while right-click -> Repo Browser on an existing working copy shows an incomplete repo browser view with a few folders but no files.

This is when the repo is on a server using Windows authentication and the users are working on machines that are on the same network but not members of the same domain. Before the security patches this gave a username/password popup when trying SVN operations and after entering the correct DOMAIN\user + password the operations completed without any problems. Now after the updates there is no user/password dialog, the operations just fails immediately. It looks like the TSVN client just tries to authenticate with the user logged into the Windows 10 machine, in this case Microsoft Accounts that are not part of the windows domain without letting the user enter any other credentials.

We are using TSVN 1.9.4 build 27285 on Windows 10 x64 with Anniversary Update and we have reproduced this behavior on multiple machines with the same security updates.
