Black screen after login on Windows 11: How to fix it

A black screen after signing into Windows 11, usually with just a mouse cursor floating on an empty display, points to the desktop shell failing to load. The login itself succeeds, but explorer.exe or the graphics stack stalls before the taskbar and icons appear. The fix depends on whether you can reach Task Manager, whether the issue started after an update, and whether Fast Startup is involved.

⚡

Quick answer: Press Ctrl+Alt+Delete, open Task Manager, choose File > Run new task, type explorer.exe, tick “Create this task with administrative privileges,” and press Enter. If the desktop returns, disable Fast Startup to prevent it from recurring.

Reset the graphics driver first

Before anything else, try the built-in keyboard shortcut that restarts the display stack without rebooting. Press Windows + Ctrl + Shift + B. You should hear a short beep and see the screen flicker. If the desktop appears, a stalled GPU driver was the cause and no further action is needed for that session.

If nothing happens, cycle the display output. Press Windows + P, then tap P again and press Enter to rotate through PC screen only, Duplicate, Extend, and Second screen only. This rules out a misrouted signal to a disconnected monitor.

Restart Windows Explorer from Task Manager

The most common cause is that the Explorer shell did not launch with your user session. Task Manager can start it manually.

Press Ctrl + Alt + Delete and select Task Manager. If Ctrl+Shift+Esc works directly, use that instead.

In Task Manager, click File > Run new task. Type explorer.exe, tick the box for Create this task with administrative privileges, and press Enter.

If the taskbar and desktop appear, the shell was not auto-starting. Proceed to the registry check below to make the fix permanent. If Explorer is already running but the screen is still blank, end the explorer.exe process in the Details tab and relaunch it the same way.

Verify the shell registry value

If Explorer will not start at all, the Winlogon shell entry may be missing or corrupted. This needs to match a clean Windows 11 install.

From Task Manager, choose File > Run new task, type regedit, tick the admin box, and press Enter.

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon. Confirm the Shell value exists and is set to explorer.exe. If it contains anything else, back up the key, then change it.

Also check HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment. Confirm a string value named windir exists with the data C:\Windows. A missing windir variable has resolved black-screen-after-login cases where Explorer refuses to launch.

Reboot. You should land on a normal desktop after signing in.

Boot into Safe Mode to fix deeper issues

If the desktop never appears, even after restarting Explorer, boot into Safe Mode so you can roll back drivers, uninstall recent software, or run a system restore without the shell being involved.

On the lock screen, click the Power icon, then hold Shift and click Restart. If you cannot reach the lock screen, force shutdown by holding the power button for 10 seconds. Repeat two or three times until Windows enters the Recovery Environment automatically.

Choose Troubleshoot > Advanced options > Startup Settings > Restart. When the list appears, press 5 or F5 for Safe Mode with Networking.

Sign in. If the desktop loads here but not in normal mode, the culprit is a driver, startup app, or third-party service — not Windows itself.

Roll back or reinstall the graphics driver

Display driver conflicts are one of the top triggers, especially right after a Windows update or a GPU driver update.

In Safe Mode, right-click the Start button and open Device Manager. Expand Display adapters.

Right-click your GPU and choose Properties > Driver tab. If Roll Back Driver is available, use it. Otherwise, choose Uninstall device and tick Attempt to remove the driver for this device.

Reboot normally. Windows will install a baseline driver. If the desktop now loads, reinstall the latest stable driver from Nvidia, AMD, or Intel — matching your exact GPU model.

Turn off Fast Startup

Fast Startup is hybrid hibernation. When you shut down, Windows saves kernel state to hiberfil.sys and reloads it on the next boot. On some systems, particularly with certain motherboard firmware or GPU drivers, this reused state is what leaves you with a black screen and cursor. Disabling it forces a full cold boot every time.

Open Command Prompt or Terminal as administrator.

Run:


powercfg -H off

This disables hibernation and Fast Startup together, and deletes hiberfil.sys — freeing several gigabytes equal to your installed RAM. Reboot to apply.

If you prefer a GUI: open Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable, then clear Turn on fast startup (recommended).

🔁

Note: On an SSD, a cold boot typically adds only 3 to 10 seconds versus Fast Startup, and it avoids a long list of driver and update bugs that persist across shutdowns. A true restart always bypasses Fast Startup, which is why “just restart it” often fixes things that shutting down and powering back on does not.

Uninstall recently added software

If the black screen started after installing a program, a shell extension, filter driver, or security tool is likely hooking into Explorer. Third-party folder protection, screen recorders, virtual display utilities, Explorer replacements, and some antivirus products have all been linked to this behavior.

Boot into Safe Mode, open Settings > Apps > Installed apps, and uninstall anything added in the days before the problem started. Reboot after each removal and test. If a specific program is the trigger, reinstalling it will reproduce the black screen — confirming the cause.

Repair system files and the image

Corrupted system files can prevent the shell from initializing. Running the built-in repair tools in order resolves most cases.

Open Command Prompt or Terminal as administrator (from Safe Mode if needed).

Run:


DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Let both commands finish. DISM repairs the underlying Windows image; SFC then uses that clean image to replace damaged system files. Reboot.

Use System Restore if it started after an update

When the black screen began immediately after a Windows update or driver install, a restore point from before that change is the fastest fix.

From the Recovery Environment, go to Troubleshoot > Advanced options > System Restore and pick a restore point dated before the issue appeared. This rolls back drivers, updates, and registry changes without touching your personal files.

If an update is confirmed as the trigger, you can also uninstall it from Troubleshoot > Advanced options > Uninstall Updates, then pause Windows Update for a few weeks to avoid reinstallation while a fix is prepared.

Blinking underscore cursor on a black screen	BIOS cannot find boot device	Check boot order and drive connection in BIOS
One-minute delay then desktop loads	Delayed user profile or AppX provisioning	Wait out the delay; check for cumulative updates

When to consider a reset or clean install

If the shell still will not load after rolling back drivers, running DISM and SFC, disabling Fast Startup, removing recent software, and attempting System Restore, you are likely dealing with a corrupted user profile or a broken component store that repair tools cannot reach.

Create a new local administrator account first — from Task Manager, run control userpasswords2 or use net user NewName Password /add followed by net localgroup Administrators NewName /add in an admin prompt. Sign in to the new account. If it loads a normal desktop, the original profile is the problem and you can migrate your files over.

If a fresh profile also shows the black screen, use Settings > System > Recovery > Reset this PC and choose Keep my files. As a last resort, perform a clean install from a Windows 11 USB created with the Media Creation Tool. Back up data from Safe Mode before doing this.

Known issue note: Microsoft has acknowledged black-screen-after-login reports tied to mid-2025 Windows 11 cumulative updates, involving the App Readiness service and delayed shell startup on imaged enterprise deployments. If you are on a managed device, check with your IT team before making registry or driver changes, because a pending servicing fix may already be in the pipeline.
