Microsoft has been tracking some odd issues that occur on Windows 7 and Windows Server 2008 R2. These bugs are not typically fixed via Windows Update, because these hotfixes should only be applied to systems that are experiencing specific problems. So if you are not severely affected by either of them, wait for the relevant service packs. Here are the four most prominent issues, listed in order of decreasing severity.
The first manifests itself when the computer crashes after it runs for some time, with the user seeing the following BSOD (the four parameters vary depending on the computer):
STOP: 0x0000000A (parameter1, parameter2, parameter3, parameter4)
IRQL_NOT_LESS_OR_EQUAL
Microsoft explains that the issue occurs because Power Manager opens an Advanced Local Procedure Call (ALPC) port and closes another port instead of closing the ALPC one, resulting in a successive memory leak, leading to an eventual crash. If you're affected, this is for you: Hotfix Request.
Few users realize the second issue is a bug. As described in KB958685, it affects all versions of Vista, Windows Server 2008, and Windows 7. If the user puts the notebook to sleep while its lid is still open and then afterwards closes the lid while the computer is still asleep, Windows will only display a blank screen and a mouse pointer upon wake. This continues until a key is pressed or the mouse is clicked. You can wait for the next software update that contains this hotfix (SP1 on Windows 7 and Windows Server 2008 R2, SP2 on Vista) or you can click this: Hotfix Request.
The third issue is described in KB978789 and specifically applies to computers with chipsets from the Intel 5 Series or the Intel 3400 Series families coupled with Windows 7 Home Premium, Professional, or Ultimate. Using a USB bulk storage device that has pending control and bulk traffic with such a Windows-based computer will result in the device becoming unresponsive, with the iPhone mentioned as a culprit.
Microsoft doesn't have a hotfix for this problem, suggesting that the user contact the computer/motherboard manufacturer for a BIOS update.
The last problem is explained in KB975360 and affects all editions of Windows 7. It is only evident with computers that have a quad-core processor and support multitouch, and involves the Microsoft Rebound game from the Microsoft Touch Pack for Windows 7 not responding if you try to launch it. Since this is entirely a Microsoft problem, here's the solution: Hotfix Request.
Microsoft is expected to offer SP1 for Windows 7 and Windows Server 2008 R2 this fall.
