I purchased a Lenovo W700 notebook computer a couple of years ago and had it configured from the factory with Windows XP. Recently, I installed a larger hard drive and installed Windows 7 32 Professional with a clean install. Lenovo had Windows 7 32 drivers for all devices for model W700 on their website, and I have installed all the latest drivers, including the latest BIOS. Later, in the course of trying to troubleshoot the shutdown delay problem, I upgraded to Windows 7 Ultimate, but it didn't make any difference with respect to the shutdown problem. The problem I'm having is that, intermittently, the computer sits at the Shutting Down... screen for about 8 minutes before the computer shuts off. Following information in this forum and elsewhere on the web, I have done the following steps: 1. I shut down all startups and non-Microsoft services (except for Norton AntiVirus, which I could not shut off), essentially a clean boot, but the problem still occurred. I subsequently uninstalled Norton AntiVirus and installed AVG Anti-Virus, thinking maybe that Norton AntiVirus was causing the problem, but the problem still occured. 2. I've done a number of xbootmgr traces; the shutdown duration always is in the 16-17 seconds range, even when the computer sits at the Shutting Down... screen for 8 minutes. 3. I've enabled verbose event logging; all programs and services seem to shut down in a timely manner, even when the computer sits at the Shutting Down... screen for 8 minutes. 4. I've looked at the Event Logs; even in the cases when the computer sits at the Shutting Down... screen for 8 minutes, the duration between the Event ID 1074 (initiation of shutdown) and Event ID 13 (operating system shutting down) is approximately 15 seconds. When shutdown is delayed, it is happening after logging Event ID 13 when event logging has already terminated. When I loaded Windows 7, I had a Blu-ray drive in one of the serial-ATA bays. Subsequent to the installation, I inserted a serial-ATA hard drive in the bay, so during bootup, I get an error message that the cdrom drivers failed to load. I also get an error on bootup that the HP CUE discovery service hung on startup. I am normally running the computer in a dock with external devices, but the problem still occurs when I run the computer outside the dock with nothing external connected to the computer. I sweep the computer every week for malware and viruses and delete files in the temp folder and temporary internet files every time I shut down the computer (at least once a day). There is one other strange thing happening. I also have a MacBook Pro running Windows 7 32 using Bootcamp. When I look at the c:\users\dwwalker\AppData\Local folder, there is always a subfolder with an alphanumeric name, e.g., {914702C8-CD5D-4970-BEB8-451429C61959} that appears to be empty, but there is always just a single folder of that type. However, on the Lenovo W700 computer, there are multiple folders of that nature that accummulate over time, all of which seem to be empty. Please let me know what further information would be helpful. At this point, I don't know what else to try. Thanks. David
