• Added build constraints to Windows specific files.
• Fixed error handling for GetFileSystemType.
• pkg/etw now supports setting a provider group ID.
• Switched from os/exec to golang.org/x/sys/execabs for launching processes. This removes a generally unintended affect where the current directory would be searched for the binary to be launched.
• Added GetFileStandardInfo which returns information from the GetFileInformationByHandleEx syscall with FileStandardInfo specified.
