As I wrote, I only see something similar on one particular system out
of 4 I tried this on. And I'm not yet sure what I see there is what
happens on Mario's system.

SHWLAPI.dll!IUnknown_QueryService+0x87 on my system where I see this.

This:
wow64win.dll+0x3fe3a
wow64win.dll+0x1aeac
wow64.dll!Wow64SystemServiceEx+0xd7
wow64cpu.dll!TurboDispatchJumpAddressEnd+0x2d
wow64.dll!Wow64SystemServiceEx+0x1ce
wow64.dll!Wow64LdrpInitialize+0x42a
ntdll.dll!RtlIsDosDeviceName_U+0x23a27
ntdll.dll!LdrInitializeThunk+0xe
USER32.dll!DispatchMessageW+0x5c
SHLWAPI.dll!Ordinal173+0x287b
ntdll.dll!RtlInitializeExceptionChain+0x63
ntdll.dll!RtlInitializeExceptionChain+0x36
Mario, can you tell if you see similar things on your system? I
suggest you verify that you have the same issue, by installing the
Process Explorer and looking in the Properties for the Emacs process,
in the Threads tab. There you should see a new thread created each
time w32-shell-execute is invoked, and also the symbolic Start Address
of each such thread.
