Question about Outlook Express

Old title: Win Live Mail

I am unable to figure out how to uninstall Windows Live Mail 2012 from my Win 10 upgrade. I was convinced that WLM wouldn't work with Win 10 so I installed Thunderbird which I am very happy with. WLM attempts to open now and then and I'd love to uninstall it. The Windows Essentials help site is no help. Thank you.

So, just yesterday (June 13,2016) I started having issues from Movie Maker not wanting to save my videos. It plays them fine with no problem. It started freezing and saying that it cant start, when its half way through saving. Today, it won't save at all, and immediately states it can't start.
I am sort of across a lot of topics here, but it mainly concerns Movie Maker.

So how does system and compressed memory come in? It is running 16 to 23% CPU constantly, never going down below 16% but has went to 36% CPU a few times. It hits 36% CPU mainly when I'm trying to save a video in Movie Maker, in which it causes Movie Maker to go from using 90% CPU to 64%. This is when my ENTIRE computer screen, keyboard, and touch pad mouse freezes. It will set frozen 5-20 minutes. Sometimes it unfreezes, and other times it won't. When Movie Maker isn't open, my mouse will glitch, and sometimes just freezes completely, along with the screen when system and compressed memory gets near 23% CPU.

My computer is a Dell Inspiron 15 laptop, with an AMD A6 Quad core processor, and AMD Radeon R4 Graphics. I have tried a clean boot, and the same thing happens. I checked to see if everything was up to date, it is.

I am using Movie Maker, which came with Windows Essentials 2012

Operating system is Windows 10, updated almost a year ago (I think is the time frame) from Windows 8.1

I asked my boyfriend, who is studying to be a computer support tech, and he's just as stumped as I am on this.

Please help,

So I have a video of a screen capture. Within the screen capture there is a section of video that had low audio. Is there a way to split the section that contains the quiet video, and increase that selections volume? 

In other words. There is a section in the video that is quiet. I want to make it louder. I have tried using the Video Tools -> Video volume option and increased the volume. This did not work. 

Help please and thank you
