Windows 10: Windows 10 launches extra thread when running an executable

Hi there. I observed that when creating an executable with Visual Studio, Windows 10 will launch one (sometimes even two) extra thread. This happens even for the simplest program:

int main()
{
return 0;
}

If you break on return 0, Visual Studio will show two threads: the main thread, and an extra unknown one.

Has anyone encountered this yet? Do you know the cause and if it should/will be fixed?

Thanks.

Run as admin fails

When I attempt to run anything on my fresh Windows 10 install it freezes the launching process for a minute then an error pops up, saying that the executable could not be found. This happens with all of the executables I have tried.

 

Zoo Tycoon 2 does not launch in Windows 10

Dear All,

I have installed Zoo Tycoon 2 on my Window 10 Desktop PC. When trying to launch the app, I keep getting error message "You need to be logged in as an admin to launch this app". However, I am already logged as an admin. It does not help also when I select
"Run as an admin" in properties of the executable file.

I used to have same problem in Windows 8.1 before upgrading to 10. The game used to run fine in Windows XP.

Thank you in advance for any idea!

Kind regards,

Marcin

 

What kind of program are you creating? That looks like C, are you sure you aren't creating a managed app by mistake?

 

You can create/test C/C++ in visual studio.. I use CodeBlocks.

 

Visual studio has bugs with build 10049



If you are a developer, Microsoft recommends you do not upgrade...

 

No, it's not a managed app. I created a C++ General Empty Project.

 

Thanks for the information Doug.. good man!! *Biggrin

 

No, Visual Studio 2015 Has problems, there's no mention of Visual Studio 2013 or earlier.

 

True, but the op didn't mention his version *Wink

 

I used Visual Studio 2008.

 

And this is a preview OS....Give feedback to MS *Wink

 

VS 2008 is no longer in Mainstream support, and will be completely end of lifed by 2018. I wouldn't expect much, if any traction on a VS2008 issue in Windows 10.

 

How should I? Do they have an official way or just the Windows Feedback app which they'll probably never read?

 

Hi

Windows uses some tracing mechanics which internally uses a threadpool. It looks like it is created even before kernel32.dll gets loaded. I'll let you know if I find out more.

Update:
threadpool is used not only for tracing subsystem, but it is also used to parallelize static imports (i.e. - the dlls your app depends on). Looks like it's the new default to have a few threads hanging around even if you don't use any multithreading in your applications at all.
