Hello RameshV1555,
Try this video fix and see if it helps you:

Try run the Windows Update and download and install all updates.
Make sure update your graphic card driver too.
You may open start and search for feedback and open the Feedback Hub app and report this issue.
RameshV1555 Editing the registry as shown in the video is unnecessary. In task manager>Processes tab, right click the 'Desktop Window Manager' entry and select 'Go to details'.
This will take you to the 'Details' tab of Task Manager, showing a detailed view of the running 'DWM.exe' process. There may be one or more instances of DWM.exe running, and if so, right click on the process showing the highest memory usage, and select 'End task'.
Your screen will turn black (with the exception of the mouse cursor) as DWM.exe restarts for a moment, but will result in returning to the screen as you left it and clearing the memory without needing to reboot your system.
Again, this is NOT a permanent solution, but a quick fix until Microsoft and Intel can address what is causing the memory hole issue.
