Windows user name must contain English alphabetical characters only, without any space. Inappropriate user name may result in problems with app update, timer, etc.

A bad example would be "medıa & İnternatıonal" (lower case ı and upper case İ, space between characters, non-alphabetical characters).

A good example would be "averygoodusername".

Enter the command above in the Run dialog box via WIN+R and click the OK button.

Uncheck the box next to Users must enter a user name and password to use this computer from the Users tab.

Select OK at the bottom of the window.

When the Automatically sign in box appears, enter the username you wish to use for your automatic login, followed by the password in the next two boxes.

Select OK to save and close the open windows.

Restart your computer and make sure that Windows automatically logs you in. You may catch a glimpse of the sign-in screen, but only long enough to see it log you in without you having to type anything!

In the Services window, scroll down to Windows Update and turn off the Service. 

To turn it off, right-click on the process, click on Properties and select Disabled.

You need to also disable the Windows Update Medic Service or WaaSMedicSVC.
