New computer what software is needed

Hi I just built a new computer and am thinking of all the software I need. It's an intel Intel Core i5 3570K with onboard graphics Gigabyte GA-Z77-D3H MB, Intel Z77 Chipset, Socket 1155.
I have avast antivirus,
windows 7 home
office
vlc media player
winrar
Itunes
utorrent
snipping tool
rainmeter
Is there something important that I am missing?
sorry if its vague it just seems that i am missing something (my old laptop got beer spilt on it in a party and is completely ruined)
thanks in advance

As long as you have the software that you use and are able to do what you need with the PC then I see no other software that you need.

I recommend Ditto

But do remember even though you can get things you want now, as you use your computer you will probably need more now.
