M.Office Process / Task Manager

Hello everyone. I recently start having a problem which I believe is related to a process...
I'm not an expert at all, usually I go on forums and I can fix stuff by myself by reading and studying other people's similar problems. But this time I couldn't find anything like this.

So, I use my computer every day, and recently I noticed something coming up (for a few seconds) and then disappearing right away. Here's a screen:

I don't have M. Office installed on this computer. So I really don't know what is this about.
Plus if I'm playing a game or watching a movie, it will interrupt that app, making it a bit annoying now.
I also took some screens of the task manager, in case it can help with the problem:

AS far as I can see, nothing is jumping out at me. But you do have some high disk usage on a few screen shots which tells me you have some stuff accessing your HDD a lot. You also have some high Memory usage. How much RAM do you have installed?

As for you Office question....it looks to be installed as I have Office 2016 Pro Plus and have the exact same process listed. You may want to check your installed programs for the control panel/uninstall programs and see what you actually have installed. If it's installed it will be listed in the uninstall list.

Sorry, my mistake. Office it's installed on this laptop, I just never used it. It came with the laptop... I just opened the first time and gives me that ''choose a trial version or buy the product'' etc. So like I said, never used it, and I don't understand why that pop-up task keeps showing... :/
