64-bit Windows 7 is booting fast on my Core i7 computer with solid state drive until I install the ethernet device driver. I tried several different ethernet vendors include Intel Gigabit Ethernet with the same result: Windows 7 boots fast after clean install, but installing the ethernet device driver and I'm looking at the Windows Start Up Logo for a good minute-and-half to two minutes on bootup. I can have the ethernet card in the system with each clean installion without the ethernet device driver installed and it boots fast. (I also think the Windows desktop might be running a little bit slower after the ethernet device driver is install.) Any suggestion for getting pep back?

1. Set the logging in F8 boot logo and see, what happens: Enable boot logging http://windows.microsoft.com/en-US/windows-vista/Advanced-startup-options-including-safe-mode 2. Are there any traces in event logs? 3. As in 1 give a try to Disable driver signature. Reveal your findings here. Regards Milos

Hi, How about booting in Safe Mode with networking? Please install the driver from computer manufacturer's website. Meanwhile, set a static IP for a test. Niki Han TechNet Community Support

I don't have access to static IP on this network account. I neglected to mention the motherboard boots UEFI only, no rom bios MBR booting. I measured the following boot speed by stopwatch from pressing the power on button to the Winodws log in screen Clean installation/ethernet is an unrecongized device: 21 seconds After manufacturer website device driver installed: 1 minute 34 seconds After disabling ethernet device driver through device manager: 1 minute 32 seconds Booting Safe Mode with networking: 46 seconds

Hi, It seems the issue mostly caused by other factors rather than network adapter driver. "Safe Mode with networking" still loads the network adapter driver. At this time, I suggest you perform clean boot and disable your security software for a test. Meanwhile, please refer to the following article to check related boot time log. http://itexpertvoice.com/home/what%E2%80%99s-taking-so-long-how-to-fight-slow-startup-times-in-windows-7/ Niki Han TechNet Community Support
