Let's face it, WordPress does upgrades right... You just hit "Upgrade" then "yes" and watch a little twirlie thing and voilla! Come on Drupal, Can't we have this feature too? Well, as it stands the process is very manual. Here are the most basic steps:

• Login to your Drupal, realize your version is out of date and that you have to upgrade. This part's easy, you will see a red message at the top "upgrade immediately" it says...
• Click on the "upgrade" message and it will show you a link for where to download the latest version

1. Download the most recent version in the tar.gz and unzip it
2. Connect to your website using FTP, download the "sites" directory
3. Backup your current database... in case something goes wrong in the upgrade
4. Login to your drupal instal with the admin account, take the site offline by going to Administer > Site maintenance
5. Disable all of the add on and custom modules by going to Administer > Modules
6. Enable one of the default drupal themes... I don't always do this but it just makes it less likely you'll get locked out or something if the theme isn't compatible
7. Now, what I do is delete everything in my local directory besides the "sites" folder that we just downloaded in step 2
8. Copy all of the new Drupal files and folders from the download from step 1. into your website directory
9. Upload all of these new files over your existing site files (aside from the "sites" folder, that would be redundant)
10. go to your website url /update.php and follow the instructions
11. Success! Now you've updated your site and can reinitiate the theme and custom modules

That's a long frustrating process but hopefully this step by step tutorial helps you guys out, Drupal has an official instruction "howto" that comes as a readme called UPGRADE.txt but it's so long and boaring. I'm not responsible for you crashing your site by following my shortlist :)
