SYMPTOMS

Consider the following scenario:

  • You have a computer that is running Windows 7 or Windows Server 2008 R2.
  • You install hotfix KB976427.
  • You enable the Require a password on wakeup option.
  • You resume the computer from Sleep (S3) or from Hibernation (S4).

In this scenario, the logon screen may appear two times. Therefore, you have to enter your credentials two times.


CAUSE

This issue occurs when there are multiple pending lock signals to be processed when the user is logging in. In this situation, the WinLogon state machine logs the user off.

Windows 7 and Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    6.1.760 0.20xxxWindows 7 and Windows Server 2008 R2RTMLDR
  • GDR service branches contain only those fixes that are widely released to address widespread, extremely important issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
