Fix Closing MacBook Lid Shutdown Issues in Windows 7

Microsoft recently released the vaguely-named "reliability update" (KB977074) for Windows 7 and Windows Server 2008. Shortly after installing this update, I noticed unstable and unreliable behavior on my MacBook (mid-2008, 2.4GHz, Mac OS X 10.6.2, running Windows 7 Pro x64 under Boot Camp). For example, I noticed that frequently, when I close the lid on my MacBook under Windows 7, it would completely power off the machine and I would lose any unsaved work. Upon boot up, Windows 7 would show the message stating that it was not shut down properly or that "Windows shutdown unexpectedly." I suspected that this was related to a recent Apple Boot Camp driver update; however, in my case, I have determined that Windows update KB977074 appears to be at fault. After uninstalling KB977074, I can now close the lid of my MacBook and it goes into sleep mode properly without powering off. Resuming from sleep is also working properly again. It appears that there are a number of folks experiencing problems relating to KB977074 as reflected in the Microsoft TechNet forums. In fact, it is advised that you uninstall this update if you are having any of these associated problems.

Well, my MacBook is still not going into sleep mode in Windows 7 whenever I either close the lid or select sleep from the Windows menu. I've spent hours troubleshooting and I still haven't figured it out.

Thanks for your blog post. I'm having this same problem too - see http://superuser.com/questions/119189
I'm going to uninstall it and hopefully it'll work for me as well as it worked for you

Cool, thanks for the link. A week ago my MacBook was still having problems sleeping. After the latest round of updates from Microsoft (released 3/9/2010), I can properly sleep the MacBook by closing the lid in Windows 7. Here's to hoping that things stay normal for the foreseeable future. I'll post if anything changes.

Unfortunately, my MacBook does not sleep properly. It seems to be random and I can't predict why it is forcing a power off some times. I tried to replicate the problem by closing the lid with the power adapter plugged in and unplugged, but that didn't seem to make a difference.
