Attention Maplers,
In order to maintain the security and stability of MapleStory, we will be updating the Minimum System Requirements for MapleStory in an update scheduled for early October. Starting from that update, MapleStory will no longer be supporting operating systems below Windows 10. If you are using Windows 8.1 or below, you will be able to resume normal play after upgrading to Windows 10 or higher. For more information on upgrading Windows, please visit the Microsoft website.
Thank you for your cooperation,
The MapleStory Team
