These problems occur when running 32-bit applications on the 64-bit version of Windows 10 and when the window class of the application’s scroll bar is set to “USER32.DLL SCROLLBAR”. Problems have also been observed in other applications that use HScrollBar and VScrollBar controls to implement scroll bar functions.
This update also fixes the problem of increased memory usage when developers create a scroll bar control in their application. Microsoft has also improved Windows OLE, the so-called compound document, which is a security feature.
In addition, there are security fixes for the universal Bluetooth driver. In addition to these quality improvements, it seems that Windows 10 Build 18363.1556 also supports “news and interests” for more users.
