Tool to clip segments of a video newbie here,

I want to remove some segments of an MP4 video I have. Which easy to use tool would you recommend. Preferably free.

I'm using Windows.
You can always try this one for example:

But as will all "free" software, be aware during installation if you need to opt-in or out of any added software, tool-bars and so forth.
