Here's my collection of security updates for XP 64 SP2, also compatible with Windows Server 2003 SP2 64-bit, with all security updates up to this month (March). With this, you can have an up-to-date install and don't need to go to Windows Update anymore to download who knows how much, and then install it all, so it saves a lot of time Premium content which requires a validation is not included. Also not included are updates to Windows Update, as they're different for XP 64 and Windows Server 2003 64-bit, so you would need two different packs with them included. Download here btw: You can also use RyanVM Integrator 1.5 for this.
