No, unfortunately there is no demo version anymore, and the viewer edition is not free anymore either. What was that line of code in user32 intended to fix? I might be able to fix the regression myself if you could explain that line's purpose. I have a little bit of Windows programming experience.
The patch has fixed an application (a proprietary one I can't mention here) which was creating a popup window and during its initialization/creation/ activation changed focus/active window to another one. Setting focus was breaking keyboard input for that other window.
