Hi Ben, I only have a small number of CS 13 clients, as most of my Clients are still CS 12.31, but I can see I now have the registry key on my CS13 systems:- HKEY\Software\Microsoft\Windows\CurrentVersion\QualityCompat For my ignorance, why does this particular registry key need to be created by F-Secure? We have been "playing" on some test servers with some of the Microsoft patches just released for Windows 2008 & Windows 2012, & the patches seem to install find WITHOUT the registry key being present. So the fact the patches have seemed to install ok mean that although the patch has “worked”, could it be that the Anti-Virus software itself could then potentially cause issues? So when the registry key is there, the Anti-Virus software has also been patched to the right level before the MS patch goes on it, so it should then not cause any issues? Thanks Alan
