Firstly, I just want to say that I hope everyone is staying healthy and have not been affected by the coronavirus outbreak.

Someone told me that there is a Microsoft critical update that needs to be installed for certain windows 10 users. It is called CVE-2020-0796. I am included in this update since I have win 10 version 1903 x64. What is this update and should I be concerned with any of my personal data being compromised? How do I perform this update?
