What writes the following log files:- WBEMCORE.LOG; WinMgmt.log; Setupapi.log. They seem to have error messages & are getting bigger.
examples of entries are:

WBEMCORE.LOG
Two providers supplied conflicting instances for key Name="C:\\WINDOWS\\SYSTEM\\ir32_32.dll"
.....msyuv.dll
Core physically unloaded!

WinMgmt.log
core is being shut down by WinMgmt.exe, it returned 0x0

Setupapi.log
Munged cmdline: C:\WINDOWS\SYSTEM\CMDNINST.EXE C29AE650 00000001 00000002
EXE name: C:\WINDOWS\SYSTEM\CMDNINST.EXE
The file (c:\windows\inf\machine.inf) is not digitally signed, ignoring driver date.

An unsigned or incorrectly signed driver (c:\windows\inf\machine.inf) was installed for Advanced Configuration and Power Interface (ACPI) BIOS. Error 0x800b0001: Unknown trust provider.

Am I heading for trouble? Like most I have the odd unexplained hang or hiccup.

MS KB article about the Setupapi.log

BEGIN ARTICLE

Incorrectly or Improperly Signed" Files Listed in the Setupapi.log File (Q268606)

--------------------------------------------------------------------------------
The information in this article applies to:


Microsoft Windows Millennium Edition


--------------------------------------------------------------------------------


SYMPTOMS
When you open the Setupapi.log file after installing Windows Millennium Edition you notice that various entries show "Incorrectly or improperly signed."



CAUSE
The Setupapi.log file is created at the end of Setup and it is not possible to verify that the files are signed during Setup because the cryptography files are not yet installed or initialized.



RESOLUTION
Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
The entry "Incorrectly or improperly signed" in the Setupapi.log file does not impact the system performance in any way.

To tell you the truth I haven't found any useful info on the other two logs.

>>>WinMgmt.log
core is being shut down by WinMgmt.exe, it returned 0x0

If you are not experiencing any prolems than I wouldn't be to concerned about this message. I think it has to do with what is called debugging and this info is mostly useful to developers.
