When you open the %SystemRoot%\Setupapi.log file to troubleshoot installation and setup issues, no registry information is present.

To configure verbose logging:

1. Open a CMD.EXE window.

2. Type the following command and press Enter:

REG ADD HKLM\Software\Microsoft\Windows\CurrentVersion\Setup /V LogLevel /T REG_DWORD /F /D 0x0000FFFF

NOTE: To turn off verbose logging:

REG ADD HKLM\Software\Microsoft\Windows\CurrentVersion\Setup /V LogLevel /T REG_DWORD /F /D 0

NOTE: Verbose logging will grow the %SystemRoot%\Setupapi.log file to ~ 4 MB.
