Detailed Description

a stream's lines into the application installation log at an event level, beside its other sinks: what a driver package installer reports reaches the log Windows keeps of installations, a custom action without a session included

The log is windir%\INF\setupapi.app.log. An application's entry reaches it through LOGTOKEN_UNSPECIFIED alone: LOGTOKEN_SETUPAPI_APPLOG and LOGTOKEN_SETUPAPI_DEVLOG write nothing, and the device installation log (setupapi.dev.log) takes no entry of an application. An entry holds at most 336 characters; SetupWriteTextLog (forwarded to devrtl) formats wide, a narrow string argument is hs.

What is written is set in HKLM\Software\Microsoft\Windows\CurrentVersion\Setup (REG_DWORD):

• LogLevel 0xUUUUGHVW: VW the application log, GH the device log - 0 its default (application log TXTLOG_SUMMARY, device log TXTLOG_DETAILS), 0x01..0x0F the log off, 0x10..0x7F on at event level V (G); the value absent or 0 both at their defaults
• LogMask: the event categories written, absent all of them, 0 none
