[User380]

Hi.

I recently did a clean reset my laptop and it installed windows 8. It was running on windows 8.1, but when running windows update it gives a 80070436 error. 

I have tried many suggestions from different forums but nothing works.

Any help would be appreciated

Thanks

When deleting windows update cache it displays:"System error 5 has occured."

@User380, It seems you are encountering a "System error 5" while trying to delete the Windows update cache. This error typically indicates a permissions issue. To resolve this, you can try several steps. Here’s how to potentially resolve this issue:

Delete Windows Update Cache with Administrator Privileges:

Open Command Prompt as Administrator:

• Press Windows Key + X and select Command Prompt (Admin) or Windows PowerShell (Admin).
• If prompted by User Account Control (UAC), click Yes to proceed.

Stop Windows Update Service:

• In the Command Prompt, type the following commands and press Enter after each one:
  net stop wuauserv
  net stop bits

Delete the Cache:

• Navigate to the Windows Update cache folder. You can do this by typing:rd /s /q %systemroot%\SoftwareDistribution

Restart Windows Update Service:

• After deleting the cache, restart the services with the following commands:
  net start wuauserv
  net start bits

Close the Command Prompt:

• Type exit and press Enter to close the Command Prompt.

By following these steps, you should be able to delete the Windows Update cache without encountering "System error 5".

I followed the steps and everything was successful, however it is still giving the same error.

 

It shows this when installing update but gives the 80070436 error

@User380, thanks for the update—and I totally get how frustrating this can be, especially after trying so many steps.

Since the basic fixes didn’t solve it, here are a couple more things you can try:

1. Manually install the update that’s failing:
Sometimes specific updates cause this error. Head over to the Microsoft Update Catalog, search for the update code (like KBxxxxxxx), and download/install it manually.

2. Upgrade to Windows 8.1 (if possible):
Windows 8 is no longer supported, which might be affecting the update process. If you can, upgrading to Windows 8.1 through the Microsoft Store may bypass the issue entirely and improve compatibility.

Hope this helps! 

Take care, and have an amazing day!
