I've been looking into some of the Windows updates, and I came across KB 4474419. I understand that it's related to Secure Hash Algorithm 2 (SHA-2) code signing support, but I'm a bit confused about its specifics and implications. Can someone explain what exactly KB 4474419 does and why it's important? Also, is there anything I should be doing after installing this update to ensure my system is secure and functioning properly? Any potential issues to watch out for? Thanks in advance!
