title: Remove the shadow effect on windows WINAPI
body: <p>Is there a way I can remove the drop shadow effect on a window in my program? 
  I'm using the Win32 API under VC++, Platform: Windows 10.</p>
  
  <p>I know I can use <code>SystemParametersInfo()</code> with <code>SPI_SETDROPSHADOW</code> to set it as <code>FALSE</code> but I was wondering if there is an option to only affect a single window as this affects all windows?</p>
  
  <p>This shows the shadow that shall be removed (no CS_DROPSHADOW used):<br>

  <p>This shows the shadow that is visible if <code>CS_DROPSHADOW</code> is used:<br>

  <p><code>SystemParametersInfo()</code> with <code>SPI_SETDROPSHADOW</code> turns off both shadows, but there does not seem to be a windows style or windows class style to disable the shadow that is drawn when <code>CS_DROPSHADOW</code> is not used.</p>
