Faster MSIX is a faster, multithreaded MSIX packer. It uses Intel ISA-L Fast
Deflate while keeping standard MSIX compatibility. After installation, normal
makeappx pack commands are automatically handled by Faster MSIX; unsupported
commands are passed to the original Windows SDK tool.
Run FasterMSIX.exe and select Install and Register. Open a new terminal
after installation.
makeappx pack /d C:\path\to\payload /p C:\output\App.msix /oThe payload folder must contain a valid AppxManifest.xml. The resulting
package is unsigned and can be signed separately with SignTool.
