Microsoft is helping Windows 7 customers deal with poor startup performance; "You experience a long startup time on a Windows 7-based computer that has an unused external SATA port. This issue occurs because the Microsoft Advanced Host Controller Interface (AHCI) initialization timing does not align with the SATA specification," reads Microsoft.

For those not familiar with SATA, the acronym stands for Serial Advanced Technology Attachment, and is essentially a consumer mass storage interconnect designed for the ATA command protocol.

The hotfix is only intended to resolve the glitch described above, and with Microsoft advising customers that experienced no Windows 7 startup performance degradation to dodge the fix altogether.
