Windows boot loop after update

Symptoms

• System restarts repeatedly after an update
• Windows never reaches the login screen
• Automatic repair fails
• Boot loop began immediately after updating

Why This Happens

Updates modify core system files and boot configuration. If an update fails partway through, Windows may be unable to complete startup. Common causes include: - Corrupted system files - Driver incompatibility - Interrupted updates - Disk errors

Step-by-Step Troubleshooting

Step 1: Enter Windows Recovery Environment

• Force shutdown during boot three times.
• Access recovery options.

Step 2: Run Startup Repair

• Select Startup Repair.
• Allow Windows to attempt automatic fixes.

Step 3: Uninstall Recent Updates

• Use Advanced options.
• Remove the latest quality or feature update.

Step 4: Use System Restore

• Restore to a point before the update.

When This Topic Is Limited

If recovery fails, reinstalling Windows may be necessary.

Summary

Boot loops after updates are caused by incomplete system changes. Removing the update or restoring the system resolves most cases.
