How to install a patch on a computer game?

If I installed a fresh copy of a game like GTA IV or Crysis and I want to install a patch, what should I do?



Do I need to download all the patches from the first patch upto the latest patch?

OR

Can I just download the latest patch and install that and everything will be covered?How to install a patch on a computer game?
Depends on the game and the patch. All patches should say individually how they are to be applied, whether online or in the readme file.



If it doesn't, you can probably assume you can just apply it straight.
