Looking at the registry problems, they should hopefully be simple enough to fix.
Copy the data from inside the Code Box below into an
Elevated Command Prompt window, and post the results.
It should fix two of the errors, and give us enough data to fix the other two....
Code:
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\PackageDetect\Microsoft-Windows-Foundation-Package~31bf3856ad364e35~amd64~~0.0.0.0" /v WUClient-SelfUpdate-Aux-AuxComp~31bf3856ad364e35~amd64~~7.6.7600.256

Here are some instructions to make life easier
1) To open an Elevated Command Prompt Window (the ECP window), click on Start, All Programs, Accessories – then right-click on Command Prompt, and select Run as Administrator. Accept the UAC prompt. 2) To run the commands easier, highlight the block of commands, and right-click on the highlight – select Copy. In the CP Window, click on the black/white icon at top left – select Paste. The commands will run but may not complete the last command, so hit the Enter Key once. 3) To copy the results... click on the Black/White icon in the top left, and select Edit... 'Select All', and hit the Enter key - then use Ctrl+V or r-click+Paste to paste it into your response.
