Fixes an issue in which communication transactions between IEEE 1394-compatible devices and a computer that is running Windows 7 or Windows Server 2008 R2 are never completed. This issue occurs when the computer is not the IEEE 1394 bus manager.

In these configurations, an attacker may be able to search for BitLocker encryption keys in system memory by spoofing the SBP-2 hardware ID by using an attacking device that is plugged into a 1394 port.

Move the Oemn.inf and Oemn.pnf files back to the %Systemroot%\Inf folder. Use Device Manager to remove the VGA video adapter, and then restart the computer. Windows Plug and Play locates the OEM video adapter and reinstalls the OEM drivers automatically.

Describes a problem that Isochronous transfers over the IEEE 1394 bus may not successfully finish when the device driver detaches and reattaches the buffer in Windows 7 and in Windows Server 2008 R2. Provides a hotfix and a workaround for this problem if you cannot immediately apply this hotfix.

Describes methods to prevent users from connecting to a USB storage device that is connected to a Windows XP-based, Windows Server 2003-based, or Windows 2000-based computer.

Fixes an issue in which a computer that is running Windows 7 or Windows Server 2008 R2 crashes and you receive Stop Error 0000003B (Error 0x3B) (SYSTEM SERVICE EXCEPTION). This issue occurs when you use some IEEE 1394 devices.

This article covers error codes that are generated by Device Manager in Windows. You probably reached this article because Device Manager or another tool like DXDiag reported an error code, and you are not sure how to resolve it.

Use this app to try to recover lost files that have been deleted from your local storage device (including internal drives, external drives, and USB devices) and can’t be restored from the Recycle Bin.

If your Microsoft or Surface mouse or keyboard isn’t working, doesn’t appear in the list of Bluetooth devices when you pair the mouse, or you see an error message during pairing, here are some troubleshooting steps to help.

Microsoft is aware of new variants of the class of attack known as speculative execution side-channel vulnerabilities. The variants are named L1 Terminal Fault (L1TF) and Microarchitectural Data Sampling (MDS). An attacker who can successfully exploit L1TF or MDS may be able to read privileged data across trust boundaries.
