WinSCP stops working after Windows Update KB5132043 (November 2026)

Hi,
After installing the November 2026 Windows 11 security update KB5132043, WinSCP (version 6.7) completely stopped working on my system.
As soon as I uninstalled KB5132043, WinSCP started working normally.

Thanks for your report.
Can you be more specific about the problem? Do you get any errors? Does WinSCP fail to start? Or does it fail to connect?
I do not have system compatible with KB5132043 (Windows 11 Enterprise family). But I have KB5132061 installed on my Windows 11 Pro, which should contain the same secure boot fix. And with it, WinSCP works without any problems.
Tested both with the latest WinSCP 6.7.1 and your WinSCP 6.7.
