[SOLVED] COMPONENTS hive registry seems to be corrupted

[chiragw]

Hi there! I'm having an issue with Windows Update that isn't allowing me to download any of the Windows Update.

I'm still getting the error code 0x800703F1 while trying to update. However, I'm able to update MS products without any issue.

I followed the instructions on the sticky so I have the information that is required - SFC Fix and CBS logs!

Error - Cumulative Update for Windows 10 Version 1607 (KB3176938) - Error 0x800703f1

Appreciate your help on this issue and let me know if you need the COMPONENTS hive or anything else.

My components hive can be accessed from the below link:

Step 1 - Replace Components Hive Manually

Warning: this fix is specific to the user in this thread. No one else should follow these instructions as it may cause more harm than good. If you are after assistance, please start a thread of your own.

1. Download COMPONENTS.ZIP and save to your desktop.
2. Right-click on it and select Extract all.... Make sure the "Show extracted files when complete" is checked and click Extract.
3. Now we have the COMPONENTS file that we will be using to replace your current one.
4. Navigate to C:\Windows\System32\config
5. Right-click on the current COMPONENTS file and select rename. Rename it to COMPONENTS.bad.
   Note: If you get an error that the file is in use, reboot your computer and then try again.
6. Take the file from the Components folder on your desktop and paste it into C:\Windows\System32\config

Step 2 - DISM /RestoreHealth Scan

1. Right-click on the Start
   
   button and select Command Prompt (Admin)
2. When command prompt opens, Copy (Ctrl+C) and Paste (Right-click > Paste) the following command into it, then press Enter
   
   Dism /Online /Cleanup-Image /RestoreHealth
   
   
3. When DISM finishes scanning your component store, zip up and attach your CBS log to your next post:
   
   C:\Windows\Logs\CBS\CBS.log

DISM worked just fine and completed without any error. Logs below:

Looks good :thumbsup2:

Please check for Windows Updates and install any that are offered.

Thank you so much for your help and time. Really appreciate it. It looks good so far and is atleast downloading the updates now. :thumbsup2:

Just out of curiosity, may I know what was the issue and is there any way to avoid it in future?

Marked thread as SOLVED :wave:

Unfortunately I don't know what the cause is so I don't have any suggestions to avoid the problem.

What I do know is that the header of the Components Hive becomes corrupted, it can be 'fixed' by loading the hive with Regedit on Windows 7 or using a tool like the Hivex.
