Client requests take a long time and memory leak occurs when you run an application in Windows 7 or Windows Vista

Symptoms
This issue occurs if the application is based on Microsoft Component Services (COM+) and is registered as single-threaded in Windows 7, Windows Server 2008 R2, Windows Vista, or Windows Server 2008. Eventually, the application may freeze. 
Cause
This issue occurs because Object Contexts sometimes aren't released.
Resolution
To fix this issue, we have released a hotfix for Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008.

Windows 7 and Windows Server 2008 R2 file information and 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's 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:
    VersionProductMilestoneService branch
    6.1.760 1.18xxxWindows 7 and Windows Server 2008 R2SP1GDR
    6.1.760 1.23xxxWindows 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" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes aren't listed, are signed with a Microsoft digital signature.
