Do NOT load Arduino IDE from the Windows Apps store, it will not provide full access to your sketches.

You can find out what version you have by going to Control Panel > Apps & Features, if you have Arduino IDE with Arduino LLC in shadow lettering underneath it as a second line in the title, it is the Windows Apps store version. Delete it and download the Zipped windows installer version from the arduino website.

If you have trouble connecting the Arduino to the computer look at the Arduino Troubleshooting section on their web site

Adafruit Industries have Learn Arduino written by Ladyada  which is a series of 3  lessons with detailed information on the Arduino, how to set it up, load software and do basic activities. There is a menu on the side of the left side of the lesson. Options include viewing as a Single Page or downloaded as a PDF. Do these 3 lessons first, then go to Simon Monks Lesson 1. Blink.

Ladyada’s Learn Arduino – Lesson #0

Ladyada’s Learn Arduino – Lesson #1

It seems that the Blink sketch has been updated in the IDE versions, so the code you see  in the IDE version 1.8.33 is different to the code you see in the IDE version 1.6.11 in The Parts of a Sketch section in Ladyadas Lesson 1#, where you see the Blink code.  You can change the delay in the new IDE 1.8.33 and do this lessons exercises. To learn how to change the LED port, do Simon Monks Lesson 2 LED’s  below.

Arduino Libraries guide on Adafruit details how to install libraries on your computer

LearningArduino_SimonMonk Sketch files, unzip, add to Arduino>Library directory

Simon Monk has 18 Lessons for Learn Arduino 
Note: These Lessons were written using an early IDE version so you will need to use Simon Monks code for these lessons, not the newer IDE sketch code if it is different, as in the Blink example.
The Arduino kit that Hugh has sent out to you will get you started on the first three lessons. As you scroll down each lesson, you will see breadboard views showing all of the connections.The remainder of the lessons in this series are designed to lead you through various aspects of both electronics and programming the Arduino. In the workshop are :
74HC595 Shift Registers
which can be used to expand the number of digital outputs from the Arduino.
Electret Microphones, Light Dependant Resistors, Stepper motors, Colour Sensor, 2 x 37in1 Sensor Kits for Arduinos, MT3608 Stup Up Boost Converters .

Warning: There are a lot of contacts on the bottom of the Arduino board that can short out, use insulated rubber feet or nylon standoffs or sit the board on paper to protect the Arduino so contacts are not shorted out !
