Process that runs in Untrusted integrity level is reported as an AppContainer after you install KB2532445 in Windows 7 SP1 and Windows Server 2008 R2 SP1

Applies to: Windows 7 Service Pack 1Windows 7 ProfessionalWindows 7 Enterprise More

Symptoms


Assume that you install hotfix 2532445 on a Windows 7 Service Pack 1 (SP1)-based or Windows Server 2008 R2 SP1-based computer. You have a process that runs in the Untrusted integrity level (you can use a program such as Process Explorer to check the integrity level). In this situation, the process is reported incorrectly as an AppContainer, which is a process-isolation environment that is introduced in Windows 8.


Note If you have an application that calls the GetTokenInformation function by using the TokenIsAppContainer class as documented in TOKEN_INFORMATION_CLASS enumeration, you will receive an incorrect result.

Cause


This issue occurs because the definition of the TOKEN_INFORMATION_CLASS enumeration is changed after hotfix 2532445 is installed.
