[FIXED]World of Warcraft was unable to start up 3D Acceleration error on Windows 10

There have been reports saying that the people who have been playing World of Warcraft experienced issues while they were in game.

The game suddenly freezes and they have to close it using the Task Manager and people who face this issue usually think this issue as a normal one and try to open the executable file of the game again as if nothing happened.

The Windows Operating System blocks them from opening the file because of errors in it and the Windows OS keeps popping up an alert box stating the error statement ‘World of Warcraft was unable to start up 3d acceleration’.

Sometimes, this issue is faced only with a particular game (World of Warcraft in this case) and in some cases, this issue might just spread out and all the games which use similar feature might get blocked due to this error.
