All new computers have a built in trap. One you don't find out about till 60 days after purchase. Its called trial software (or unkindly bloatware or cr*pware!) - software pre-installed on you new PC.
The scenario is that you will be happily using Microsoft Word (or another Microsoft Office product eg Outlook) then... it wont work!
A box will popup saying "please enter the 25 character product key".
What this means is your trial has expired and you will need to purchase the product in order to keep using it. Basic versions of Office cost around $150.
The good news is that free software is available. As good or better than Microsoft Office. Examples are Open Office and Thunderbird & Gmail.
So if you come across the "60 day after problem" dont worry, you have two options - go and purchase the full version or just download some free software.
