What is Wowexec.exe?Function?

Sometimes my PC will run this program but it is not stop by itself.
 
Hi Andy,

WOWEXEC is short for "Windows On Windows Execution Process" and it provides
support for 16-bit Windows applications and ntvdm (Virtual DOS Machine).



Regards,
 
wowexec.exe is used in conjuction with ntvdm.exe to run old DOS
applications.

[[MS-DOS and 16-bit Windows programs actually run as a Win32 process. The
program that creates the virtual MS-DOS environments for these to run in
(NTVDM.EXE) is a Win32 program. A virtual DOS machine (VDM) is created for
the program, so it thinks that it is running on a machine by itself.
However, the virtual machine is a normal 32-bit Windows NT process and is
subject to the same rules of preemptive multitasking as is other programs.
However, this only applies to MS-DOS programs. ]]

[[To run 16-bit Windows applications, NT uses a VDM that contains an extra
software layer called the Win16 on Win32 (WOW) layer. Although the VDM for
Windows shares some of the code for MS-DOS VDM, all Windows applications
share the same VDM. The reason this is done is to simulate the environment
that 16-bit Windows applications run in. Because Windows applications might
want to communicate with one another, a single VDM is used. Each 16-bit
application runs as a thread of the VDM; however, the WOW layers ensures
that only one of these threads is running at any given time. ]]
