Why Should you activate your copy of Windows?
Activation is the process of making sure that you have a Legally Valid License, from Microsoft Corporation, for the copy of the Windows Operating system you are using, for example, Windows XP, Windows Vista, Windows 7 etc.
Generally, when you buy a new computer or when you buy a copy of Windows XP or Vista or Windows 7, you will have 30 days to ‘Activate” it. If you do not activate it within 30 days, you will not be able to use all the features of the software – until you activate it.
You should activate it so that you will be able to use all the features of Windows as well as receive all the updates from Microsoft for the product from time to time. This will keep your computer safe from Viruses, Spyware and other problems.
