Windows 10: Unable to log into computer after latest Windows10 update.

Updated my computer a few days ago with the latest update for windows 10 which i have been running for a while. After updating which took around 12 hours (give or take) (let it run overnight) I went to try it out and I was unable to log in. Even changed my password with no difference. Everytime I try to log in i keep getting a blue screen and it says "The user profile service failed the sign in. User profile cannot be loaded". I upgraded to windows 10 using the free upgrade if that makes any difference.

Unable to log into the computer after latest Windows 10 update

Hi Jim,



Thank you for contacting Microsoft Community. I understand that your computer are unable to access any files or applications after installing
latest Windows Update. I will surely help you to fix this issue.



This issue could have occurred due to conflict between third party applications.



I suggest you to boot the computer to Safe Mode and check if the issue occurs. If the issue do not occur in Safe Mode, I suggest you to set the computer in a clean boot state and check if it helps.



Step 1:

I suggest you to refer the article and check if it helps.

Step 2:

If the issue do not occur in Safe Mode, perform a clean boot and check. Setting the system in a clean boot state will help to identify if any third party applications or startup items are causing the issue.
