I changed my user account name and now my laptop is unable to boot up.

Please tell me a solution, how can i solve the problem.

Hi Susan;

Thank you for updating me with that information, I would recommend creating a new profile user rather than modify the username because this will effect with registry keys files and could be effect changing from permanent to a temporary profile user.

The solution is login as an admin or Administrator then follow one of the methods below:-

Method 1:-

• Hit "Windows Logo" and type "Control Panel"
• Click "User Accounts" then click "Add or Remove Account"
• Create a new account then put it as the Admin group.
• Log-off then log-in with the new one and delete the old profile

Method 2:-

• Hit "Windows Logo" and type "Control Panel"
• Click "System and Security" then click "Administrative Tools" and open "Computer Management"
• On the left-sidebar click "Local users and Group" and Right-click on "Users" select New User
• Create the user then Right-click the one-created select "Properties"
• Select "Member Of" then click "Add" then click "Advanced" then click "Find Now"
• A list will appear such highlight on "Administrators" then click OK then OK and OK
• After that log-off and log-in with the new one then you can remove or delete the account.

Let me know if you need any assistants

How can i do this methods, my laptop won't start at all. When i try to start my laptop it says "your pc ran into a problem and needs to restart". Automatic repair won't work and restart wont work.

Hi Susan;

This will show you how to access or login on Safe Mode with Network then you can do of the methods above:-

• Hold down the power button for 10 seconds to turn off your device.
• Press the power button again to turn on your device.
• On the first sign that Windows has started (for example, some devices show the manufacturer’s logo when restarting) hold down the power button for 10 seconds to turn off your device.
• Press the power button again to turn on your device.
• When Windows restarts, hold down the power button for 10 seconds to turn off your device.
• Press the power button again to turn on your device.
• Allow your device to fully restart to enter WinRE.
• Click "Troubleshoot" then click "Advanced options" then click "Startup Settings" then "Restart"
• After your device restarts, you'll see a list of options. The preferred option is to select number 5 or press F5 for Safe Mode with Networking
• Once your device is in safe mode do the methods and see if you are able to log-in and creating a profile user.
