My favourite piece of software is Notepad.
It is a free Microsoft application and you will find it by clicking on Start and type Notepad
Why is it so good? How many times have you found something on the Internet such as the correct spelling of ‘Arnold Schwarzenegger’? You copy and paste it into your Word document only to find that it has font changes, hyperlinks etc attached to it. However, if you paste it into Notepad and then do a [Ctrl + A] and a [Ctrl + X] from there, you will find where ever you paste into, the text will be clean and matching the format of your document!
