Summary: Start button dead or menu closes instantly? Restart Explorer, run Start troubleshooter, repair shell settings—no reinstall.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
You click **Start** or press the **Windows** key and nothing happens—or the menu flashes open and vanishes. Search inside Start may be dead as well. This is almost always the shell (`explorer.exe`) or a broken Start layout, not grounds for reinstalling Windows.

> **Taskbar frozen but Start works?** See [taskbar not working or disappearing](https://www.mytechnician.tech/tips/fix-windows-11-taskbar-not-working-disappearing/). **Search broken but Start opens?** Try [fix Windows 11 search](https://www.mytechnician.tech/tips/fix-windows-11-search-not-working/).

## Step 1: Restart Windows Explorer
Fixes a large share of cases in five seconds.

1. `Ctrl + Shift + Esc` → **Task Manager**.
2. **Processes** → right-click **Windows Explorer** → **Restart**.
3. Test **Start** and the **Windows** key.

If Explorer is not listed: **Run new task** → type `explorer.exe` → **OK**.

## Step 2: Sign Out, Then Restart Properly
1. `Ctrl + Alt + Del` → **Sign out** → sign back in. This clears a stuck shell session after sleep or an update, and is quicker than a reboot.
2. If that does not do it, choose **Restart** rather than **Shut down**. With Fast Startup on, a shutdown restores the same broken kernel state; a restart does not.

If it broke immediately after Patch Tuesday, also read [fix Windows 11 after a bad update](https://www.mytechnician.tech/tips/fix-windows-11-after-bad-update-rollback/).

## Step 3: Remove Third-Party Start Replacements
StartAllBack, ExplorerPatcher, Start11, Open-Shell and similar tools hook directly into the shell and break with almost every Windows update. A dead Start menu right after an update on a PC running one of them is that tool, not Windows.

Uninstall it from **Settings** → **Apps** → **Installed apps**, restart, and test. Reinstall only after the vendor has published a build for your Windows version.

## Step 4: Re-register the Start Components
In **Terminal (Admin)**:

```powershell
Get-AppxPackage Microsoft.Windows.StartMenuExperienceHost | Reset-AppxPackage
```
```powershell
Get-AppxPackage Microsoft.Windows.ShellExperienceHost | Reset-AppxPackage
```

Restart. If those error, run the broader re-registration—it keeps your files:

```powershell
Get-AppxPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
```

Expect several red errors about packages that cannot be re-registered; those are normal.

## Step 5: Rebuild the Start Layout Database
A corrupted tile database stops Start opening while everything else works. Close all apps, then in **Terminal (Admin)**:

```cmd
taskkill /f /im StartMenuExperienceHost.exe
```

Then delete the database folder at:

```
%LocalAppData%\Packages\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy\TempState
```

Restart. Windows rebuilds it. You may need to re-pin your tiles, which is the only cost.

## Step 6: Repair System Files
```cmd
DISM /Online /Cleanup-Image /RestoreHealth
```
```cmd
sfc /scannow
```

Run DISM first, then SFC, then restart. Details: [repair Windows 11 with SFC and DISM](https://www.mytechnician.tech/tips/how-to-run-sfc-dism-repair-windows-11/).

Stuck updates can break the shell too—[fix Windows Update stuck](https://www.mytechnician.tech/tips/fix-windows-update-stuck-windows-11/) if patches never finish installing.

## Step 7: Check the Critical Services
`Win + R` → `services.msc`. These must be running:

* **Application Identity**
* **User Manager**
* **Tile Data model server** (older builds)
* **Windows Search**, if search inside Start is the broken part

Set anything stopped to **Automatic** and start it.

## Step 8: Test a New User Account
This separates a broken profile from a broken installation.

1. **Settings** → **Accounts** → **Other users** → **Add account** → **I don't have this person's sign-in information** → **Add a user without a Microsoft account**.
2. Sign into the new account and test Start.

**Works there** → your original profile is damaged. Moving to the new profile is usually faster than repairing the old one; copy your data across from `C:\Users\<old>`. See [fix "signed in with a temporary profile"](https://www.mytechnician.tech/tips/fix-temporary-profile-windows-11/).

**Broken there too** → the installation itself is damaged. Go to the last step.

## Step 9: In-Place Repair Install
Download the Windows 11 ISO from Microsoft, mount it, run `setup.exe` from inside Windows, and choose **Keep personal files and apps**. This rebuilds every shell component without touching your data: [reinstall Windows without losing data](https://www.mytechnician.tech/tips/reinstall-windows-without-losing-data/).

## Working Around It Meanwhile
* `Win + R` for Run, then type program names directly.
* `Win + X` opens the power-user menu with Terminal, Device Manager, and Settings.
* `Win + I` for Settings, `Win + E` for File Explorer.
* Pin the apps you need most to the taskbar.

## What Not to Do
* **Don't delete registry keys from forum posts.** Broken `StartMenuExperienceHost` keys are hard to reverse.
* **Don't run `Remove-AppxPackage` on StartMenuExperienceHost.** You will be left with no Start menu at all and no easy route back.

## After It Works
Keep the Start grid small—very large pinned layouts slow the menu's load. If it breaks again after every sleep cycle, update the BIOS and graphics drivers, and turn off Fast Startup: **Control Panel** → **Power Options** → **Choose what the power buttons do** → untick **Turn on fast startup**.
