Missing boot-start driver bthex.dll
(This may be repeated....if so, sorry!)When I start my computer (with
Win XP Home SP3 installed), just after the BIOS info screen and before Windows even kicks in, I get a white progress bar at the bottom of the screen that fills up over about 20 minutes before the usual Windows logo/start screen appears. Looking at the event viewer for the System I find that "boot-start or system-start driver "bthex" was not found. Looking in the Registry indicates that bthex is expected to be found in Win\System32\Drivers. It is not there, so something has suddenly deleted\renamed it or something. I have put my installation DVD in the drive and tried a repair but this driver cannot be located there, and I have googled for it but with no luck. Can anyone suggest where I might find this system file, or maybe even search for it on their own Syste32 folder and make it available to me?? Many thanks for any help in advance. Richard |

If it's a driver it would be a .sys file (not a .dll). A search for this file yields no results, often an indication that the file is virus or malware related. I would suggest that you make sure that the machine is free of any pests. Where *exactly* in the registry did you find reference to this file? It could be that your Anti-Virus tools have removed an infection and that the entry is just a remnant. John |

I have run Anti MalwareBytes AntiMalware, SuperAntiSpyware and Kaspersky's Virus Removal Tool. The first two indicate no problems, but Kaspersky *DID* identify some threats and *DID* remove them. If it was as you suggest the remnant of an infection,why would my boot-start continue for so long to look for it, and how can I tell it not to, and get my boot time back to acceptable levels? 25 mins is just too long especially when reboots are being asked for by other (OK) programs. Thanks for your help. Richard |

If it's a driver it would be a .sys file (not a .dll). A search for this file yields no results, often an indication that the file is virus or malware related.

If I delete all these references, could that help?? Is it in the CurrentControlSet? Look for phantom devices in the Device Manager and see if any make mention this BTHEX driver: Device Manager does not display devices that are not connected to the Windows XP-based computer http://support.microsoft.com/kb/315539 This little batch file will automatically set the Device Manager to show phantom devices and open it for you: ---------------------------------------------------- set devmgr_show_nonpresent_devices-1 start devmgmt.msc ---------------------------------------------------- You cannot delete the keys in the Enum section because you do not have permission to do so, grant yourself the necessary permissions and you will be able to remove the keys. Before you do that keep in mind that there is a good reason why only the System account has permission to delete keys in the in the \Enum branch! It would be best to remove the device in the Device Manager instead of removing it from the Enum keys. Before you change the permissions and delete keys please read the following: Enum http://technet.microsoft.com/en-ca/l.../cc976176.aspx System and Startup Settings http://technet.microsoft.com/en-us/l.../bb742541.aspx HKEY_LOCAL_MACHINE\SYSTEM\Select http://technet.microsoft.com/en-ca/l.../cc978528.aspx John Yes - it is in CurrentControlSet under /Enum/Root/LEGACY_BTHEX/0000. No mention in Device Manager, or after running your batch file. I won't try to meddle with Enum, but how do I grant myself permission if I did want to?? I will read the articles you mention, but since this is the file that is causing my 20 min startup delay, ex-infection or otherwise - how do I get rid of my system searching for it?? Thanks again. The registry permissions are just like regular NTFS file permissions, just right click on the offending key and select Permissions... If you are convinced that this is the culprit and if you cannot remove the device from the Device Manager then just grant yourself full control on the key and delete it. For the time being remove it in the CurrentControlSet only! If the Windows installation balks at its removal (when you reboot) just boot to the Last Known Good Configuration. John Thanks John - I will try that and report back, assuming I don't mess something up! Will take a while. Thanks again. You're welcome. See my other post about disabling/removing the service. John |

The problem is more likely to be caused by the status of the service in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es branch, I suggest that you remove or disable the service there. To disable the service set its Start value to 4. John Well, Having deleted it from the CurrentControlSet and rebooted, the problem is still there, but Event Viewer no longer reports a problem in looking for bthex. So I presume bthex, whatever it is, is *not* the reason for my slow progress bar in booting up. Any ideas as to what it might now be? Could it be something to do with Power On Self Testing, or if not is there any way of diagnosing why this has suddenly started occuring? Cheers. Richard |

I think that what you are seeing is part of the Windows boot process rather than the POST routine, an easy way to tell would be to press/tap the F8 key when the computer is booting and see how long it takes for the advanced Windows boot options show up. Or put a second (phony) line in the boot.ini file and see how long it takes for ntldr to parse and present the boot menu. John |
