A practical guide to the hidden Emergency Restart option in Windows 10 and Windows 11, including when it helps, what it does, and what to check after the reboot.
Emergency Restart is a hidden Windows restart option available from the security screen that appears after pressing Ctrl + Alt + Del. It is designed for situations where Windows is still responding enough to show the security screen, but the desktop, apps, Start menu, or taskbar are frozen.
Unlike a normal restart, Emergency Restart does not politely wait for programs to close. Windows immediately starts the restart process and warns that any unsaved work may be lost. For that reason, it should be used only when a standard restart is impossible or unreliable.
The option is accessed after pressing Ctrl + Alt + Del, then holding Ctrl while clicking the power icon.
Windows does not wait through the usual app-close prompts. It starts the restart sequence immediately after confirmation.
It is usually preferable to holding the physical power button because Windows still initiates a software restart path.
Emergency Restart is not a daily shutdown method. It is a recovery option for cases where Windows is partially alive but the normal interface is not usable.
The Emergency Restart option is hidden behind a keyboard-and-mouse combination. The steps are the same in Windows 10 and Windows 11.
Emergency Restart key sequence
Ctrl + Alt + Del
Hold Ctrl
Click the Power icon
Click OK on the Emergency restart screen
If a full-screen game, video editor, browser, or remote desktop session is frozen, try the same sequence. The secure attention shortcut Ctrl + Alt + Del is handled by Windows at a low level, so it may still work even when the foreground program does not respond.
If the mouse pointer is frozen but the keyboard still works, try using Tab, arrow keys, and Enter on the security screen. However, Emergency Restart is much easier when the mouse or touchpad still responds because the hidden trigger requires clicking the power icon while holding Ctrl.
When you confirm Emergency Restart, Windows immediately begins restarting the computer. It does not behave like a normal restart that gives apps time to ask whether you want to save changes.
| Item | What Happens | Risk Level |
|---|---|---|
| Unsaved documents | Open changes may be lost if the program did not autosave them. | High |
| Frozen applications | Windows stops them as part of the restart process. | Medium |
| Windows services | Services are stopped as Windows restarts, but not as gracefully as during a normal restart. | Medium |
| File transfers | Copy, move, download, sync, or backup jobs can be interrupted. | High |
| Windows update | Updates may resume, roll back, or require repair depending on the update stage. | High |
| System drive | The restart is still initiated by Windows, so it is usually safer than pulling the power cable. | Medium |
Different restart methods have different risk levels. Choose the least aggressive option that still works.
| Method | How to Start It | Best For | Data Safety |
|---|---|---|---|
| Normal restart | Start menu → Power → Restart | Routine restarts, updates, driver changes, normal maintenance | Safest |
| Command restart | shutdown /r /f /t 0 |
Responsive Windows session where you can still run commands | Medium |
| Emergency Restart | Ctrl + Alt + Del, hold Ctrl, click Power | Frozen desktop, broken Start menu, blocked normal restart | Medium |
| Power button shutdown | Hold the physical power button for several seconds | System does not respond to keyboard, mouse, or display | Risky |
| Pulling power / battery | Disconnect power source or remove battery where possible | Last resort only | Most risky |
If Windows is still responsive enough to open Command Prompt, PowerShell, or the Run dialog, you can force a restart with the command below. It is not the same as the hidden Emergency Restart screen, but it is useful when the graphical restart button does not work.
Force restart from Command Prompt or PowerShell
shutdown /r /f /t 0
/f option forces running applications to close. Remove /f if you want Windows to give apps a better chance to close normally.
Emergency Restart requires the Windows security screen to appear. If the keyboard shortcut does nothing, the system may be more deeply frozen, the display driver may be locked, or the computer may have stopped responding at the hardware level.
If the disk light is active or Windows is applying updates, wait before forcing anything. Interrupting update or disk activity can cause additional repair steps on the next boot.
Least riskyPress Ctrl + Shift + Esc. If Task Manager opens, end only the frozen program instead of restarting the whole PC.
Targeted fixIf the PC is completely frozen, hold the physical power button until it turns off. Then wait a few seconds and turn it on again.
Last resortTry waking or refreshing the display before forcing a shutdown. Press Win + Ctrl + Shift + B to restart the graphics driver. You may hear a beep and the screen may flash. If the display returns, save your work and restart normally.
Restart graphics driver shortcut
Win + Ctrl + Shift + B
Try a different USB port, disconnect external hubs, or use a wired keyboard if possible. On laptops, check whether the system reacts to the built-in keyboard. If nothing responds, use the physical power button as the final option.
After the computer starts again, check whether the issue was a one-time freeze or a repeated stability problem. The goal is to identify whether a driver, update, app, disk issue, or overheating problem caused the lockup.
Open Reliability Monitor
perfmon /rel
Open Event Viewer
eventvwr.msc
Check and repair Windows system files
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
Scan the system drive online
chkdsk C: /scan
Kernel-Power, Display, Disk, WHEA-Logger, service crashes, and application hangs.
If you needed Emergency Restart once, it may simply have been a temporary application hang. If you need it repeatedly, treat it as a sign of a deeper stability problem.
The following commands and tools can help you collect basic information after a forced or emergency restart.
| Tool or Command | Purpose | How to Run |
|---|---|---|
perfmon /rel |
Shows a timeline of crashes, app hangs, update failures, and hardware errors. | Run dialog, Search, Command Prompt, or PowerShell |
eventvwr.msc |
Opens Event Viewer for detailed Windows logs. | Run dialog, Search, Command Prompt, or PowerShell |
sfc /scannow |
Checks protected Windows system files and repairs many common integrity problems. | Administrator Command Prompt or Terminal |
DISM /Online /Cleanup-Image /RestoreHealth |
Repairs the Windows component store used by system file repair. | Administrator Command Prompt or Terminal |
mdsched.exe |
Starts Windows Memory Diagnostic to check RAM after a reboot. | Run dialog or Search |
resmon |
Opens Resource Monitor to inspect CPU, memory, disk, and network usage. | Run dialog or Search |
shutdown /r /f /t 0 the same as Emergency Restart?

Emergency Restart in Windows is a useful hidden recovery option when the desktop is frozen but the security screen still opens. It is faster and usually cleaner than cutting power, but it can still close apps abruptly and discard unsaved work.
Use Ctrl + Alt + Del, hold Ctrl, and click the Power icon only when Windows cannot restart normally. After the reboot, check Reliability Monitor and Event Viewer if freezes happen again.
