Hi @SEONGDONG CHEON ,
You can remove the watermark by going to the Registry Editor, open a Command Prompt and run the following command: regedit
.
Once there go to HKEY_CURRENT_USER\Control Panel\Desktop, then find the PaintDesktopVersion
registry key and change the value to 0.
Once done, restart your computer and the watermark should be gone.
