Quick answer
Most often it's enough to restart the Windows Explorer process in Task Manager or restart the computer, because that restarts the Start menu interface. If that doesn't help, check system file integrity with `sfc /scannow` and `DISM`, update Windows and test another user account. Only if that fails too, move on to more complex measures.
How to recognize the problem
- Clicking the Start button doesn't open the menu or the menu opens and immediately closes
- The keyboard doesn't respond to the Windows key and search doesn't start anything
- Other taskbar icons work, but Start and search don't respond
- The menu opens empty, without tiles and the app list
- The problem appears after an update or installing a new app
Most common causes
Windows Explorer process is stuck
The Start menu interface is run by the Windows Explorer process. When it gets stuck, the Start button stops responding even though the system behind it is fine.
Corrupted system files
A failed update or power interruption can leave corrupted files that the Start menu uses, so it doesn't start or closes immediately.
User profile problem
If the issue occurs only on one account, the part of the profile that stores Start menu settings is corrupted, not Windows itself.
Incompatible app or setting
Some apps for customizing the look and "optimizing" the system modify the taskbar and Start menu, which after an update causes malfunction.
Step-by-step fix
- 1
Restart the computer
First do a full restart via
Start > Power button > Restart, not just closing the lid or signing out. This restarts all interface processes and often solves the problem. If you can't open Start, pressCtrl + Alt + Deleteand choose the restart option in the bottom right corner of the screen. - 2
Restart Windows Explorer
Open Task Manager with
Ctrl + Shift + Esc, then findWindows Explorerin the process list. Right-click it and chooseRestart. If it's not in the list, choose the option to run a new task (Run new task), typeexplorer.exeand confirm. The taskbar will disappear for a moment and come back. - 3
Check if the problem exists on another account
Open
Settings > Accounts > Other usersand create a temporary local account, then sign in to it. If Start works there, the fault is in your profile, not the system. In that case, move your files to the new account or repair the profile instead of touching Windows. - 4
Check system files
Open Terminal or Command Prompt as administrator, then first run
DISM /Online /Cleanup-Image /RestoreHealth, which repairs the system image thatsfcreads files from. Then runsfc /scannowand wait for the scan to finish. After both commands, restart the computer. - 5
Install available updates
Open
Settings > Windows Updateand choose to check for updates, including optional updates. Microsoft often fixes Start menu bugs through cumulative updates. If an update gets stuck, resolve it separately before continuing. - 6
Remove recently installed customization programs
Open
Settings > Apps > Installed apps(on Windows 10:Settings > Apps > Apps & features) and remove programs that change the look of the taskbar, Start menu or "clean" the system. Then restart the computer. These programs are a common cause of failure after a major update. - 7
Restart the Start menu process
Open Task Manager with
Ctrl + Shift + Esc, then find theStartMenuExperienceHostprocess in the list. Right-click it and chooseEnd task. Then sign out and sign back in. Windows will start the Start menu process again. - 8
Check disk integrity
In the command line as administrator, run
chkdsk C: /scan, which performs a check without interrupting operation. If it reports errors, first back up important files, then runchkdsk C: /fand confirm that the repair is performed on the next restart. This step is useful if the problem repeats after every restart.
If nothing helped
When the Start menu doesn't work on a new account either, and sfc and DISM report no errors, the remaining option is to repair the system installation. Back up important files, then start the installation from Windows media and choose the option that keeps files and apps. Avoid "optimizers" and manual registry editing if you're not sure what you're doing, because that can easily spread the fault to the whole system. If the computer is on a domain or used by multiple employees, first check whether the problem is related to group policies enforced by IT administrators, because then local repairs are undone at the next sign-in.
How to prevent it
- Regularly install Windows updates and restart the computer when the system asks
- Don't install "optimization" and taskbar customization programs from unverified sources
- Create a restore point before major system changes
- Occasionally check disk health and free space on the system partition
When to call a professional
If the Start menu doesn't work even after a restart, system file check and testing on another account, or if the computer belongs to a company with a domain and group policies, it's better to contact IT support than to run a system installation repair yourself.

Will I lose data if I reset the Start menu?
No. Restarting the Windows Explorer process and the Start menu process doesn't touch your files or installed apps. Data is lost only if you choose the option to reset the system to factory settings.
Why doesn't the Start menu work only on my account?
That means the part of the profile that stores menu settings is corrupted, not Windows itself. The fastest solution is a new user account and moving files, or repairing the profile with the help of a professional.
Is it safe to run sfc and DISM commands?
Yes, if you run them as administrator and wait for them to finish. They only check and repair system files and don't delete your documents or programs.
