Some users of Windows 10 complain that the operating system has integrated a number of services into one single account. Basically, this means that you can login to your MS Office account, One Drive, but also your Hotmail account, just by entering your username and password once. Some users feel that automatic login is not a useful feature, especially if they use several different accounts at the same time.
If you want to disable automatic login, there is no need to call Hotmail support to help you. You can do this on your own by following these steps:
If everything is in order with your Microsoft account, turning off the automatic sign in should go smoothly. However, if something is not right, it can mean that your whole system is compromised. Usually, it is not something that should concern you too much, but in some cases, computer viruses are to be blamed.
Because it is always better to be safe than sorry, your best solution is to notify the Hotmail technical support about this problem. You can send them an email, explaining this problem. However, if you prefer talking to technical agents directly, feel free to call the Hotmail support number of an independent tech service.
