The other day, I downloaded and installed the May 2019 update (Build 1903) for Windows 10. After the update assistant was finished downloading the update, I clicked restart to install it. However, as the PC was shutting down, I got an error message that said "The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application". There was another error message that occured before that one, but I couldn't read it since it was quickly replaced with the one I just stated. After I clicked OK, the PC updated to 1903 and was successful. Every time I booted up my PC after that though, I got a Run Dll error which I resolved by disabling the process on startup in the task manager. However, I wonder if these messages are related.
I am worried because this sounds serious. A malicious user could gain control of my computer? What would you recommend doing to fix the issue or assure safety of using my computer again? (I have been using it for a few days since that message and everything seems normal, but I'm just seeing what someone who works at Microsoft recommends.) Thanks.
