Ouch, that stings. This puts minimum required OS at 1703 or Server 2019. SetThreadDescription is not available for static linking in 1607 and WinBox is shipped as statically linked binary. It would be possible to go around it by explicitly doing
GetProcAddress
but I am pretty confident that this is coming from Qt internals, not MikroTik code, so that makes it rather… problematic with no real good way to deal with it. I do not envy MikroTik developers on this and I would fully understand if they decided not to support it.
