Can't save username Windows 10 Tech Preview

I'm currently running the Windows 10 Technical Preview and I cannot save my username when signing into the game. I can click the check mark but after I've quit and try to go back in the settings were never saved.

Running the launcher as an Administrator does not fix this either. Just a heads up and a minor inconvenience on my end.

Hello tyniwins,

Here's how to solve your problem :

1) Start > Control Panel > Internet Options > Privacy tab > Lowers the cursor to the bottom (Accept all cookies) > Apply > OK
2) You can close the Control Panel.

EDIT : If other players have the same problem, it also works for Windows 7/8/8.1/10

Sorry for bad English, Google translation :/
