Symptoms

In Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1, you experience the following issues.

Issue 1

Consider the following scenario:
  • You have a Windows 7 SP1-based or Windows Server 2008 R2 SP1-based client computer that has multiple languages configured. 
  • You create a Remote Desktop (RD) session from the client computer to a Remote Desktop Protocol (RDP) server. 
  • You press Alt+Shift or Ctrl+Shift to switch the input language in the RD session.  
In this scenario, the language switch fails.

Notes
  • This issue occurs because the Shift key sticks during the language switch.
  • When the Shift key sticks, you also experience the following behavior:
    • You cannot type the password correctly in the RD session.
    • The input language changes during typing.
    • Multiple selections occur on every click.


Issue 2

Consider the following scenario:
  • You have some Microsoft Office applications that are published as RemoteApp applications on a Remote Desktop Session Host (RD Session Host) server.
  • You connect to the RemoteApp applications from a Windows 7 SP1-based or Windows Server 2008 R2 SP1-based client computer by using Remote Desktop Protocol (RDP) 8.0.
  • In an Office application in the RemoteApp session, you press the Alt key, and then you try to use shortcut menu.
In this scenario, the shortcut menu is no longer displayed.

Cause

Cause of Issue 1

This issue occurs because of an incorrect key scan code data is sent to the server.

Cause of Issue 2

This issue occurs because modifier keys are incorrectly synchronized when you switch between windows in the same RemoteApp client process.

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, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    6.2.920 0.20xxxWindows 7 and Windows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical 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 7 and for Windows Server 2008 R2" section.
