Make sure your settings are saving, if you exit game with alt+F4 your setting don't save.
Log in, set your settings, go to character screen then back in game, then exit the game.
If settings didn't save, go into game again, don't change settings, open the config file and find if there's the option for borderless window set off/on, close config file and set your in-game settings to what you want, then open config file and check if it saved new settings.
mine confing file shows:
SET gxResolution "1920x1080
SET gxMaximize "1"
SET gxWindow "1"
tripple buffer/vsync on for me.
Also, the config file could be set to "Read only" (right click -> properties) and somehow not save settings after you exit game.
Last, but not least, you could delete config file and force the game to create a new one for you. Better if you just backup your wtf folder and see how game handles it after it creates new config for game/chars/addons.
