Updating to windows service pack 3
The latest Service Pack for XP is finally here and it includes some minor but important updates for Windows users.
Do not install Service Pack 3 on systems with AMD chips unless a special hotfix has been applied first.
This hotfix needs to be applied before SP3, otherwise your system may get stuck in a loop and never start. The file will download directly from Microsoft's servers - you may want to shorten the file name.
PC Mechanic - Fix your PC's Windows registry errors.
The advantage of this full download is that it can be used on any system - plus it doesn't require an Internet connection to install.
However, you must have installed either Windows SP1 or SP2 before SP3.* Keep in mind that new patches made available after Service Pack 3 was released (mid April 2008) will still need to be applied.
