(Solved!) Windows Update fails, code 800B0100

[tbowers]

Win7SP1 laptop will not update, immediately gets error code 800B0100. Been through all of Microsoft's suggestions, thread lead me to tweaking.com.

Ran the Windows Repair twice in safe mode, still no luck. Below are the results of the pre scan. Any advice appreciated!

• Scan Complete - Problems Found!

│

│

• You can use the Repair Reparse Points or Repair Environment Variables tools at the bottom of this Window if needed.

│

│

• While problems have been found, you can still run the repairs in the program.

│

• But for the best results it is recommended to fix the problems reported in this scan if possible.

│

• If you need help fixing any of the items in the log, just post in the forums at Tweaking.com for help.

First grab the zip file off this page and apply the reg file it in to add the take owner ship to the right click menu in explorer.
http://www.tweaking.com/articles/pages/add_quottake_ownershipquot_to_right_click_menu_in_vista_amp_7,1.html

Once that is done go to C:\Windows\servicing\ and right click on Packages and click on take ownership. You will now be able to copy the files into that folder.

I have attached the missing files, extract the files out of the attached zip file and put them in the C:\Windows\servicing\Packages\ folder.

Then run my pre-scan again, put a check on the box to have it add the cat files back to the database.

Wow, problem solved here, and no thanks whatsoever to all of Microsoft's proposed fixes. What an incredible site/service you have here! Many thanks, and looking forward to supporting your efforts.
