Hello alan and welcome to the forum.
Please do not take offense, as I certainly do not intend any such thing but......
IF terms like "browser" and "screen shot" cause you difficulties then perhaps you might consider

You might try shopping around for a less expensive resource

OR check your local library.
When I first began I had a bookshelf full of them.
As far as "accessing Hotmail"......
Click the "Start button" (Windows logo button, bottom left most area of your desktop)
Scroll down to "Windows Accessories" and click to expand and select "Internet Explorer"
That will open "Internet Explorer" (a "browser" or web browser)
In the very top is a "URL address bar" simply type Hotmail.com there and hit the enter key on your keyboard.
Type in your Hotmail user name and password.

I would suggest using the local / native Windows 10 "Mail" app, which should, after some basic configuration, facilitate your "accessing" your Hotmail account, but that might be a bridge too far and a topic for a little bit later after you familiarize yourself a bit more with your computer, its' operating system and the user interface, which takes a bit of time, patience and effort.
