Our application suddenly keeps on freezing after some time this happens after the KB4338830 update. The unfortunately application cannot be restarted nor be closed, I suspect all of this is because the winsock(just ported) I`m using. It is written on vb.net, and the program has something to do with continuous sending and receiving data from other PCs.

Anybody encountered the same issue? solution? or at least how can I prove it is because of the update.

  • I would have mentioned that post too, since it mentions the same KB you did, but you didn't give any specifics about your project setup, so no way to know if you would have understood the issue of that post or not. – Remy Lebeau Jul 17 '18 at 02:32

Microsoft just released KB4345424 to resolve the issue. Info is from here.

For those who come from Google - KB4345459 for Windows 2008 R2 SP1 and KB4345424 for Windows 2012 R2.

KB4345421 is for Windows 10 Version 1803 and 2016.

  • This fixed my problem also. I had a Delphi app using a TIdTCPServer and it would randomly crash on shutdown. – kbriggs Aug 12 '18 at 20:39
