Symptoms
Consider the following scenario:
-
You have a computer that is running a 64-bit version of Windows Server 2008, Windows Vista, Windows 7 or Windows Server 2008 R2.
-
On this computer, a process calls the CreateProcessWithTokenW function to create a child process that runs under Windows 32-bit on Windows 64-bit (WOW64).
-
The WOW64 child process is created to redirect standard input (STDIN), standard output (STDOUT), and standard error (STDERR).
In this scenario, the redirections do not work in the WOW64 child process. Therefore, any applications or services that depend on the redirection feature do not work.
Cause
There are two Process Environment Blocks (PEBs) for every WOW64child process. One PEB is used for 64-bit processes, and the other PEB is used for 32-bit processes that are running under the WOW64 emulation environment.The CreateProcessWithTokenW function only duplicates the handles for STDIN, STDOUT, and STDERR from the parent process to the PEB for 64-bit processes. However, this function does not duplicate these handles to the PEB for 32-bit processes that are running under the WOW64 emulation environment. This behavior causes the child process that is running under WOW64 to be unable to use the redirected handles. Therefore, the redirections fail.
