The KB5000808 is a cumulative update with security fixes. Here are the direct links to download KB5000808 offline installer.
Yesterday, Microsoft released the KB5000802 update for Windows 10 v2004 & v20H2 users. Now, the same update is being released for Windows 10 v1909 users as KB5000808. The update contains both regular fixes and important security patches. Mainly, the update fixes the privilege escalation vulnerability in the print file action. Other than that, some Windows components like the kernel, fundamentals, virtualization, etc., also got security improvements.
When it comes to general improvements and fixes, the update will fix the game stuttering, HDR issues, video playback problems, and sudden app crashes. Though the update contains some security fixes, I recommend you wait for a week or so to install the update. One of the reasons being that some systems are encountering BSoD errors after installing the update.
Of course, if the automatic updates are enabled, Windows 10 will automatically download and install the update. If not, you can download the KB5000808 offline installer using the links given below and install it like any other Windows software.
