Но уж очень интересно было бы воспроизвести и опробировать именно код »

Код:

!include MUI2.nsh

!define MUI_CUSTOMFUNCTION_GUIINIT GUIInit

!insertmacro MUI_PAGE_WELCOME
!insertmacro MUI_PAGE_COMPONENTS
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_LANGUAGE "Russian"
OutFile "Example.exe"

!define WS_CAPTION 0x00C00000
!define NSD_RemoveStyle "!insertmacro _NSD_RemoveStyle_Call"
!macro _NSD_RemoveStyle_Call CONTROL EXSTYLE
  Push `${CONTROL}`
  Push `${EXSTYLE}`
  System::Store SR1R0
  IntOp $R1 $R1 ~
  System::Call `user32::GetWindowLong(iR0,i${GWL_STYLE})i.R2`
  IntOp $R2 $R1 & $R2
  System::Call `user32::SetWindowLong(iR0,i${GWL_STYLE},iR2)`
  System::Store L
!macroend

Function GUIInit
 ${NSD_RemoveStyle} $HWNDPARENT ${WS_CAPTION}
FunctionEnd
