KB5004945 is a new security update that has been released for any Windows version newer than v2004.
Users that have Windows 10 version 1909 will first get the KB5004946 patch, and then, the PrintNightmare patch will also be installed. If you are a Windows 7 user, this patch is also available for you, even though the operating system is out of support.
