Windows update errors
My Windows PC keeps failing to install the latest updates, with error codes appearing mid-installation and the update history showing repeated failed attempts, even after running the built-in Windows Update Troubleshooter.

Hi there! I’m happy to help. I’m a developer and I’ve run into similar Windows Update issues before — especially when updates fail repeatedly even after using the built‑in troubleshooter.
These steps usually fix the problem, and I’ve included how to perform each one clearly. If these don’t work, I can share more advanced solutions like manual update installation or deeper system repair.
Step‑by‑step guide you can include in your reply
01
Restart Windows Update Services
Often fixes repeated failures
Sometimes the update service gets stuck and needs a manual restart.
Press Win + R → type services.msc → press Enter
•
Find Windows Update → Right‑click → Restart
•
Find Background Intelligent Transfer Service (BITS) → Restart it
•
Find Cryptographic Services → Restart it
02
Clear Update Cache (SoftwareDistribution)
Corrupted update files are one of the most common causes of installation failures.
Press Win + R → type cmd → Run as Administrator
•
Run: net stop wuauserv
•
Run: net stop bits
•
Go to: C:\Windows\SoftwareDistribution
•
Delete all files inside the folder
•
Run: net start wuauserv
•
Run: net start bits
03
Reset Catroot2 Folder
This folder stores update signatures; resetting it helps when updates fail mid‑installation.
Run Command Prompt as Administrator
•
Run: net stop cryptsvc
•
Go to: C:\Windows\System32\catroot2
•
Delete all files inside
•
Run: net start cryptsvc
04
Repair System Files (SFC)
Fixes corrupted system files that may block updates.
Run Command Prompt as Administrator
•
Run: sfc /scannow
•
Wait for the scan to complete
•
Restart your PC
05
Repair Windows Image (DISM)
DISM repairs deeper system components that SFC cannot fix.
Run Command Prompt as Administrator
•
Run: DISM /Online /Cleanup-Image /RestoreHealth
•
Wait for the process to finish (can take several minutes)
06
Try Installing the Update Manually
Advanced Option
If automatic installation keeps failing, manual installation often works.
•
Visit the Microsoft Update Catalog
•
Search for the update code (e.g., KB5039212)
•
Download the correct version for your system
•
Install it manually
English closing sentence you can add:
If the issue continues after these steps, let me know — I can guide you through advanced repair options such as resetting Windows Update components completely or performing an in‑place upgrade without losing your files.
Sometimes, a simple restart can resolve temporary issues preventing updates.
