Hello there and Welcome. My name is Michael
This is a very common problem that happens when setting up the Microsoft account during Windows Setup.
Step 1: First of all, make sure the computer having the LOG in problem is connected to the internet, preferably hardwired.
Step 2: With secondary computer most possibly your husband's, you will have to go into outlook.com and reset the password ***** YOUR Microsoft account.
By resetting/changing the password ***** should take effect in a few seconds on the computer having the log-in issues....that's why is crucial for that computer to be connected to the internet at the time of resetting the password.
Please let me know if you require further assistance on this matter.
