Windows Driver Kit -wdk- Which Contains The Windows Asl Compiler -asl.exe- Site
Without asl.exe , you cannot programmatically compile custom ACPI tables on Windows. The open-source iasl (Intel ASL compiler) is a popular alternative, but Microsoft’s asl.exe is the only officially validated compiler for Windows hardware certification (HLK tests).
Essential for firmware engineers, but buried in a massive toolkit. Without asl
: Version 5.0 of the compiler supports the ACPI 5.0 specification , which includes hardware-reduced system designs and connected standby power models. : Version 5
The Microsoft ASL compiler is a command-line utility used to compile ACPI Source Language (ASL) files into ACPI Machine Language (AML) binaries. These AML files are then used by the system firmware (BIOS/UEFI) or loaded into the Windows registry to define hardware topologies, power management states, and device enumeration.

If you have ever needed to modify ACPI tables—perhaps to fix a DSDT override for an eGPU or to patch system firmware for a custom build—you have likely gone hunting for . This elusive tool, the Microsoft ASL Compiler
