@Christian-Ehrlicher Ah, Windows. Well, since never :-)

So How I can check memory leakage in Qt Creator running on Windows 10 ?

Thanks

Since when does valgrind run on windows?

I am the person who originally replied to @ndiwan 's "Could you please help me with how I can detect memory leak." with "Use valgrind to detect memory leakages."

I read the question carefully and nowhere did it mention using Windows. One of my pet bug-bears is if questioners cannot tell you what OS they are on for a question of this kind, why should I guess they are under Windows? Other OS people tell you what they are on, why do Windows users think people ought know they are on Windows...?

I would imagine it would depend on what compiler you have chosen to use, which we don't know....

@JonB According to Kits it's MinGW

I don't know.
And yes - my answer would also be - use valgrind or any other proper leak checker tool and how to you know that there is a memleak at all?

On Windows, it may be a good idea to use Visual Studio + Qt plugin. Visual Studio is a powerful tool and has memory check functions for C++ code.

I came across this, but never tried it by myself. Strongly recommend to use VS.
