If you're seeing a black screen after logging into Windows 10, you're not alone — it's a common issue that can happen due to corrupted system files, faulty updates, graphics drivers, or third-party software conflicts. Here’s how to fix it step by step.

1. Check if the System Is Actually Running

Sometimes, the screen looks black, but Windows is actually running in the background.

• Press Ctrl Shift Esc to open Task Manager.
• If Task Manager opens, the system is working — you just don’t have a desktop interface.
• Click File > Run new task, type explorer.exe, and press Enter. This restarts the desktop.

? If the desktop appears, the issue is likely a temporary Explorer crash.

2. Boot into Safe Mode

Safe Mode loads Windows with minimal drivers and services, helping isolate the problem.

To enter Safe Mode:

• Hold Shift while clicking Restart from the login screen (you may need to access the login screen first).
• Or, force shut down the PC 3 times during boot to trigger Automatic Repair.
• Go to Troubleshoot > Advanced Options > Startup Settings > Restart.
• After restart, press F4 or 5 (for Safe Mode with Networking).

Once in Safe Mode:

• Check if the black screen persists.
• If the desktop works fine, the issue is likely caused by a driver or startup program.

3. Update or Roll Back Graphics Drivers

Graphics driver issues are a top cause of post-login black screens.

In Safe Mode:

• Press Win X > Device Manager.
• Expand Display adapters.
• Right-click your graphics driver (e.g., Intel, NVIDIA, AMD) and choose:
  • Update driver > Search automatically.
  • Or Roll back driver (if available — useful after a recent update).

Alternatively:

• Visit your PC or GPU manufacturer’s website and download the latest driver.
• Install it manually in Safe Mode.

? Try disabling fast startup (Control Panel > Power Options > Choose what power buttons do > Change unavailable settings > Uncheck "Turn on fast startup") — it sometimes interferes with drivers.

4. Run System File Checker (SFC) and DISM

Corrupted system files can cause Explorer not to load.

In Safe Mode:

• Open Command Prompt as Administrator (from Start menu or via Run: cmd Ctrl Shift Enter).
• Run:

  sfc /scannow

• After it finishes, run:

  DISM /Online /Cleanup-Image /RestoreHealth

• Restart your PC.

These tools repair Windows system files and can resolve underlying issues.

5. Check for Problematic Startup Apps

Third-party apps (especially security tools or shell enhancers) can crash Explorer.

• In Safe Mode, open Task Manager > Startup tab.
• Disable all startup items.
• Restart normally and see if the desktop loads.
• Re-enable apps one by one to identify the culprit.

6. Create a New User Profile

Your user profile might be corrupted.

In Safe Mode:

• Open Command Prompt as Admin.
• Run:

  net user NewUser /add

• Then:

  net localgroup administrators NewUser

• Log out and sign in with the new account.
• If the black screen doesn’t appear, your original profile is damaged.

You can then migrate your files to the new account.

7. Undo Recent Windows Updates

A recent update may have caused the issue.

In Safe Mode:

• Go to Settings > Update & Security > Recovery.
• Under Reset this PC, click Get started.
• Choose Keep my files and proceed.
• Or, go to Settings > Apps > Apps & features > View installed updates, and uninstall recent quality or feature updates.

8. Perform a System Restore

If you had System Restore enabled, revert to a point before the issue.

• Boot into Advanced Options (as in Step 2).
• Go to Troubleshoot > Advanced Options > System Restore.
• Follow the prompts to restore your PC to an earlier state.

Final Notes

• If none of the above works, consider backing up your data (via another OS or recovery environment) and doing a clean Windows install.
• Always keep your system and drivers updated, but avoid installing updates right after release if stability is critical.

Basically, the black screen after login is usually fixable — start with Safe Mode and work through drivers, system files, and user profiles. Most cases are resolved without data loss.
