Message Posted I just came across this windows second edition problem you are talking about, spent a week diving into it. After running windows xp for a few months i came back to windows 98, its the fastest, lightweight and flexible system out there to date. Don't need the hype. Anyway, what you say about deleting wmiexe.exe is ok to do, but wmi.dll is what causes the startup delay with usb error detection, turn it off in the devicemanager, usb host controller, pci to usb host controller. Also when wmi.dll is not in the system directory, driver installs and some installations can't build a database to autofind these files and the pop up windows for updating drivers in device manager wont work correctly. What i did is replace Devmgr32.dll in the system directory with the file version from windows 98 1st edition and program installs use this device manager helper to find the files, I don't believe this Devmgr32.dll does much else, its only 24k in size. Windows 98 1st edition is still microsofts best! Just my opinion. Hope this helps, its been fine for me. No probs. Jack: Great tip for the database!
