🔥 How to Fix Windows 11 Errors and Crashes (Step-By-Step Guide)

Follow the solutions in order for best results.

✔ Fix 1 — Restart Your Computer

A simple restart clears temporary memory conflicts and stops minor glitches.

✔ Fix 2 — Run Windows Update Troubleshooter

1. Settings
2. System
3. Troubleshoot
4. Other troubleshooters
5. Run “Windows Update”

✔ Fix 3 — Repair System Files (SFC + DISM)

Open CMD (Admin), then run:

sfc /scannow

After that:

DISM /Online /Cleanup-Image /RestoreHealth

This repairs corrupted files causing crashes or BSOD.

✔ Fix 4 — Update All Drivers

Most errors come from drivers.

Update these first:

• Graphics driver
• Chipset driver
• WiFi + Bluetooth drivers
• Audio drivers

Use Device Manager or install directly from NVIDIA/AMD/Intel websites.

✔ Fix 5 — Uninstall Problematic Windows Updates

1. Settings
2. Windows Update
3. Update history
4. Uninstall updates

If problems started after a recent update → uninstall it.

✔ Fix 6 — Clean Boot Mode

This helps identify software conflicts.

1. Win + R → msconfig
2. Hide all Microsoft services
3. Disable all
4. Disable startup apps
5. Restart

If the error disappears → a third-party app is responsible.

✔ Fix 7 — Free Up Disk Space

Your C drive must have at least 20–25 GB free.

Clean:

• Temporary files
• Old apps
• Downloads folder
• Windows.old

Enable Storage Sense for automatic cleanup.

✔ Fix 8 — Full Malware Scan

Use Windows Security:

• Virus & Threat Protection
• Full Scan

Malware often causes crashes or update failure.

Run CMD (Admin):

net stop wuauserv
net stop bits
net stop cryptsvc
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start bits
net start cryptsvc

This fix solves 80% of update errors.

✔ Fix 10 — Repair Boot Errors (BCD Fix)

Use Windows installation media → Command Prompt:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

Fixes startup and boot problems.

✔ Fix 11 — Test RAM for Errors

1. Win + R
2. Type: mdsched.exe
