I’m trying to install the security update to patch the Sigred DNS vulnerability on our last Server 2008 x86. It’s being phased out soon but wanted to patch it regardless.

When I try to install KB4565529-x86 it says, “The Windows Modules Installer must be updated before you can install this package" so I attempted to update the Servicing Stack for 2008 (not R2) which leads me to KB955430-x86 but that also errors out saying that “This update does not apply to your system”.

How can I get this patch installed? I’ve already created the script below to put the temp fix in place but want to make sure the patch gets installed as well.


reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters" /v "TcpReceivePacketSize" /t REG_DWORD /d 0xFF00 /f
net stop DNS && net start DNS
