A few days ago we told you that Windows XP SP3 would be released April 29. Well, that just happens to be today, so we felt it was our duty to remind you. This long-awaited update to Windows XP is the last, but seriously, we are expecting this to pretty much be the best currently-available version of Windows out there, so get to downloading. If you aren’t seeing it in Windows Update yet, then just go here to grab it manually.
