Posting this here, rather than tech section so more people can see this.
SP3 is now available for download via Microsoft/Windows Update, and also available via the MS download website. The difference between the two is that the update version scans your PC, and tailors the service pack to only install whats needed, usually running about 70mb (if you keep up on your updates). The downloadable version is about 300~600mb, and for the most part will only install what is needed, but sometimes will reinstall or repair other updates. I usually recommend the full download, but there is no harm in just using the update version, id say 90% of people use that one anyway.
So far I havent read any negitive side effects of this SP, so all users should be safe, regardless of what you use your PC for.
You must be atleast running SP1; XP editions with no SPs will not be able to install SP3. It's recommended that both SP1 and SP2 are installed, but SP2 is not necessary, SP3 will fill the voids.
Notable new features include:
Black hole router detection
Network Access Protection
Credentials security service provider
Descriptive security options control panel
Enhanced security for Administrator and Service policy entries
Microsoft Kernel Mode Cryptographic Module
Installing without needing a Product Key during Setup

*USERS THAT ARE USING IE7*
If you are an IE7 user, and plan to ever uninstall it, you should first uninstall IE7, install SP3, and then reinstall IE7. SP3 causes uninstallation issues with IE7, and reverts back to older unsafe IE6 files, to fix this you will need to reinstall SP3.
Also note that SP3 is only for x86 (32bit) users, and not available for x64bit users.
