Welcome Anthony Falbo,
Thanks for reaching out to Microsoft Q&A Forum. I understand that your Windows 11 taskbar suddenly disappeared yesterday and the troubleshooting you have already tried has not restored it.
Before proceeding, could you confirm whether you can still open the Start menu by pressing the Windows key? Also, does the taskbar remain missing after signing into Windows, or does it briefly appear and then disappear?
Please make sure you already tried the Q&A Assist steps. In addition, please try the following:
1, Check whether the issue occurs in another Windows user account.
- Press Ctrl + Shift + Esc to open Task Manager.
- Select Run new task.
- Type
netplwizand select OK. - Create or use another local Windows account, sign into it, and check whether the taskbar appears.
- If the taskbar works in the other account, this helps narrow the issue to the original Windows user profile.
2, Repair Windows system files.
- Open Task Manager with Ctrl + Shift + Esc.
- Select Run new task.
- Enter cmd and select the option to create the task with administrative privileges.
- Run
sfc /scannow - Allow the scan to complete.
3, If System File Checker reports problems or the taskbar is still missing, run:
-
DISM /Online /Cleanup-Image /RestoreHealth - Wait for the process to complete.
- Run
sfc /scannowagain afterward.
4, Perform a clean boot to check whether a startup application or non-Microsoft service may be interfering with the Windows shell.
- Press Windows key + R> Enter
msconfigand select OK. - On the Services tab, select Hide all Microsoft services, then select Disable all.
- Open the Startup tab and select Open Task Manager.
- Disable enabled startup applications.
- Restart the computer and check the taskbar again.
Looking forward to your update.
