    New User in Family - Taskbar Doesn't Work

    I added my adult son to my family on the PC. I put him as an administrator. When I log on with his credentials, the system's taskbar does not work. Cortana is also missing.

    All I see in the taskbar's left side is a white windows icon, a magnifying glass, and the task mode icon. Nothing happens when I click them. On the right (wi-fi, sound, keyboard, time and date, and notifications), everything is unresponsive as well.

    I tried every solution I could find on the web such as restarting windows explorer, running the file check, and using powershell to reinstall Windows apps. None of these solutions worked. Any other suggestions?

    I started all this just so I could watch his purchased movies from XBOX One on my PC. And now I've spent like 4 hours trying to get the stupid operating system to work when I'm signed in as him. My user account still works perfect. It's just the new one I made for him that is screwed up. Hopefully someone here knows what I can do to fix it. If all else fails, can I take him off as a user without taking him out of my family and then put him back on?

    Thanks in advance for any help you can give. I'll check back tonight after work.

    This the keyboard or administrative command prompt method:

    1) win + x (simultaneously)
    2) a
    3) alt + y (simultaneously)
    4) net localgroup administrators test /add
    (substitute a name for the word test)
    5) sfc /scannow
    6) dism /online /cleanup-image /restorehealth
    7) chkdsk /scan
    8) When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on edit then copy > paste into the thread
    9) shutdown /r
    10) when the computer reboots sign on with your new name


    Steps 5 - 8 are to check the integrity of the operating system and drive.

    Step 5 said "did not find any integrity violations."
    Step 6 didn't work. It said "Error 87 The cleanup-image/restorehealth option is unknown."
    Step 7 said "found no problems."

    Because there weren't any errors (not counting the one I couldn't do), I didn't bother copying everything.

    So what now? Why did I need to add another user when what I want to do is fix the one I already have? I appreciate your help; I'm just trying to understand.

    For user accounts you can attempt to fix them by working with registry commands.
    Most people don't work within the registry and when user accounts become corrupted they are no longer used and a new one is created.

    In the left lower corner search type winver and post the windows version and build.
    The scannow command indicated that the operating system is OK.
    The dism commands are sometimes needed when scannow cannot complete or finds integrity violations that it cannot fix.

    At this time you should have been able to create a new user account with a working task bar and cortana.

    Quoting my earlier post in another thread. This should fix Taskbar / Cortana / Search functionality issues:

    In Windows, the hidden file UsrClass.dat stores quite a number of user account related information. In cases when the profile seems not be functioning properly, a simple reset (delete / recreate) of this file might in most cases solve the issue.

    Open File Explorer, type %localappdata%\Microsoft\Windows in addressbar and hit Enter to open the AppData\Local folder. Select View menu in Explorer, enable Hidden items. Now delete the UsrClass.dat file and reboot.

    When rebooted and the UsrClass.dat file is not found Windows will create a new one. Check if everything works, post here if not.

    zbook: The new profile has the same issues. Nothing works on the taskbar and Cortana is missing.

    Version 1703 (OS Build 15063.540)

    Kari: It won't let me delete. It says it is in use by system.

    Boot to Advanced Startup Options, selecting Troubleshoot > Advanced Options > Command Prompt (see tutorial: Boot to Advanced Startup Options in Windows 10 Windows 10 Installation Upgrade Tutorials ).

    When in Command Prompt, enter following command to remove Hidden and System attributes from UsrClass.dat file:

    attrib -h -s C:\Users\UsernameInQuestion\AppData\Local\Microsoft\Windows\UsrClass.dat

    When done, delete the file with following command:

    del /f C:\Users\UsernameInQuestion\AppData\Local\Microsoft\Windows\UsrClass.dat

    Restart Windows with following command:

    c:\Windows\System32\shutdown -r -t 0 -f
