What is wowpost.exe?

The genuine wowpost.exe file is a software component of Adaptec's ASPI Layer by Adaptec.
Wowpost.exe is an executable file that belongs to Adaptec's ASPI Layer, a programming interface that simplifies communications via the computer bus between a driver module and hardware peripherals. A kernel driver works directly with the operating system and hence needs to function in a very stable environment. Removing this driver may result in the application not being able to function correctly. ASPI was conceived by Adaptec and developed in 1990. It was originally created for DOS, OS/2, Windows 3.x, and Novell NetWare. It was designed to support SCSI devices (a set of standards for parallel interfaces) while support for ATAPI devices arrived later. Adaptec was an American company that developed computer storage products until 2010, when it was acquired by PMC-Sierra. Adaptec was founded by Larry Boucher in 1981 and originally focused on devices with SCSI interfaces. The company produced interface products that include SCSI, USB, IEEE 1394, iSCSI, Fibre Channel, and video. The company was based in Sunnyvale, California, USA.
