Many high-end motherboards have at least one eSATA interface, convenient for users to connect external hard drives and other equipment, but I believe many people actually do not use it, so idle, then you have not thought, it is this idle eSATA interface, may inadvertently slow down your Windows 7 system startup speed? Microsoft Knowledge Base article KB2292867 that if an unused eSATA interface is installed on a computer with a Windows 7 operating system, the system startup time can be greatly extended.

This problem occurs because the initialization timing of the Microsoft AHCI (Advanced Host Controller Interface) does not exactly match the SATA specification, and should therefore result in a longer time to detect the Esta interface.

Microsoft has released a hot fix (Hotfix), but it is not publicly available, and needs to be made available to Microsoft Support Center:
