Hello again :)
Please click start, search for regedit, and press enter.
Navigate through to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\Package_7_for_KB2656362~31bf3856ad364e35~x86~~6.0.1.1
Right click on the key, and select Permissions...
Click Advanced. Navigate to the Owner Tab. Select your username from the list, and click OK.
Back to the original window, select Users from the list, and put a check in Full Control: Allow.
Click OK.
All those extra windows should now be closed. Staying in the Package_7_for_KB2656362~31bf3856ad364e35~x86~~6.0.1.1 key, in the right hand pane of regedit, right click in empty space > New > DWORD (32-bit) Value.
Give it a name of CurrentState, and then double click on it, and give it a value of 70 (leaving the radio dot in hexadecimal).
Click OK.
Now right click on the key again > Permissions..., and take the checkbox out of Users: Full Control: Allow. Click OK again.
Done :)
Please try Windows Update again and let me know if there has been any improvement.
Finally, there is one more very important step for you to perform. Please run the attached SFCFix script (drop it onto SFCFix.exe) and copy and paste me the output.
Thank you!
Richard
