Hi,
Can you please go to Control Panel > User Accounts and Family Safety > Manage Windows Credentials
You should be able to view your saved credentials in there and check their persistence level.
Enter the credentials manually, several times, into the top and the "Generic Credentials" box.
Hope it will be helpful to you
