I'm currently going through the windows documentation, which includes the AI, android and mixed reality. So obviously, I'm downloading a bunch of software on my computer as per tutorials and documentation.
But I recently saw these two applications on my desktop, which haven't been mentioned in the documentations, or I haven't read the relevancy of these apps with Microsoft. The two applications are:
"EpicGamesLauncher.exe" or "CocosCreator.exe"
From a brief search on google.com, since I have not used them. The first looks like very similar arcade apps and thee second application, look to be just some similar developer tool. Which, I'm okay with using Blender, right now.
Are these applications directly affiliated or sponsored by Microsoft or Linux? Because on my very insecure computer, which is located in a very insecure studio that has camera recordings for only 3 minutes (when I know the device can record for more than half an hour with enough storage), these two applications were recently installed.
Or am I that lucky to have been spammed with these applications?
Thank you in advance to any replies. 
Before any users are kind to point out that I should set up a firewall, and block any unwanted applications or connections. I'm a unique case, where I believe I set my camera to record while I am away (and I know this camera records for more than 20minutes), but only shows 3 minutes of footage. And I am not currently, working on anything commercial and now, I am used to my computer processing commands that aren't mine. So I don't really see the point for network security, especially when it's time consuming. I suppose anyone, who can hack and can view other remote connections, would eventually wonder why they really need to waste their time on my computer.
