W8 Accounts

I will shortly be purchaseing a new PC with Windows 8 pre-installed.

Could you please tell me how it will be set up as far as User Accounts are concerned and what I need to do to access all the computer files, apps etc?

The thing is that I will be the only user of the PC so can I get by with just an Administrator Account or do I have to make a Standard Account?

All help much appreciated
