These errors usually appear due to driver problems, badly installed updates, or even corrupted files. But don’t worry, fixing a critical error in Windows 10 doesn’t always require formatting. Let’s look at the most effective solutions.

1. Why does a critical error appear in Windows 10?

Critical Windows failures can be caused by:

• Outdated or corrupted drivers (especially graphics drivers).
• Failed Windows updates.
• <a href="https://www.chusmeando.com/informatica-y-tecnologia/como-clonar-un-disk-duro-al-instante/” title=”How to Clone a hard drive instantly”>RAM or hard drive problems.
• Damaged system files.
• Malware or viruses.

If the error appears after installing a program or driver, that’s usually the culprit.

2. Restart in safe mode (the first mandatory step)

Before doing anything, restart in safe mode:

1. Hold down Shift + Restart.
2. Go to Advanced options > Safe boot.
3. Choose Safe Mode with Networking (in case you need internet).

If the error doesn’t appear in safe mode, the problem comes from a program or driver.

3. Update or reinstall problematic drivers

Critical errors in Windows 10 are often caused by graphics or hardware drivers. To fix it:

• Open Device Manager (Win + X).
• Look for devices with a yellow triangle.
• Right-click and choose Update driver.
• If it doesn’t work, uninstall it and restart (Windows will reinstall it automatically).

👉 Download official drivers from NVIDIA, AMD or your PC manufacturer.

4. Repair system files with SFC and DISM

If Windows has corrupted files, these commands will fix them:

1. Open CMD as administrator.
2. Type:textsfc /scannow (This scans and repairs damaged files).
3. If the error persists, try:textDISM /Online /Cleanup-Image /RestoreHealth

This may take a while, but it’s very effective.

5. Uninstall problematic updates

If the critical failure in Windows 10 started after an update:

1. Go to Settings > Update & Security > Update history.
2. Click on Uninstall updates.
3. Find the latest update and remove it.

6. Check your RAM and hard drive

Sometimes the problem is hardware:

• For RAM: Use Windows Memory Diagnostic (type it in the search bar).
• For the hard drive: Open CMD and run:textchkdsk /f /r (Restart so it can scan).

7. Restore the system to a previous point

If nothing works, restore Windows to when it was working properly:

1. Search for System Restore in the Start menu.
2. Choose a restore point prior to the error.
3. Follow the steps (you won’t lose personal files).

8. Last resort: reinstall Windows 10

If the critical error persists, you may need to reinstall:

• Make a backup of your files.
• Download the Media Creation Tool from Microsoft (official link).
• Follow the steps to reinstall without losing data (choose “Keep my files”).

Conclusion

Fixing a critical error in Windows 10 isn’t that complicated if you follow these steps. Start with safe mode, check drivers and system files, and if all else fails, reinstall Windows. Don’t give up!
