Windows 7 or Windows Server 2008 R2 crashes if a command prompt or a PowerShell console is opened and closed many times

View products that this article applies to.

Symptoms

Assume that a command prompt or a Windows PowerShell console is opened and then closed many times on a computer that is running Windows 7 or Windows Server 2008 R2. In this situation, the performance of the computer may become slow, and applications may crash.

Note This issue occurs when you use a non-English input method (such as the Japanese IME).

Cause

This issue occurs because Graphics Device Interface (GDI) objects are leaked every time that a command prompt or a PowerShell console is opened and then closed. The leak occurs in the Taskhost.exe process or the Explorer.exe process, depending on whether the language bar is displayed or not. When the number of leaked GDI object handles in the process reaches the maximum number, no more GDI objects can be created. Therefore, you experience the issue that is described in the "Symptoms" section. 

When an application receives the focus for the first time, a notification is sent to all language bars. Then, the language bars allocate GDI objects for the application. However, when a command prompt or a PowerShell console is closed, the Conhost.exe process does not send a notification to clean up the GDI objects that were allocated by the language bars. Therefore, the leak occurs.

Windows 7 and Windows Server 2008 R2 file information notes
  • 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:
    VersionProductMilestoneService branch
    6.1.760
    0.16xxx    		Windows 7 and Windows Server 2008 R2RTMGDR
    6.1.760
    0.21xxx    		Windows 7 and Windows Server 2008 R2RTMLDR
    6.1.760
    1.17xxx    		Windows 7 and Windows Server 2008 R2SP1GDR
    6.1.760
    1.21xxx    		Windows 7 and Windows Server 2008 R2SP1LDR
  • 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.
