Hi Allie,

 

Let's try a few more things to get it working. First we shall try and update the Windows Update agent and also perform a clean boot and see what happens.

How to obtain the latest Windows Update Agent

The following files are available for download from the Microsoft Download Center: For an x86-based computer Download the windowsupdateagent30-x86.exe package now.

 

 

To perform clean boot, follow the steps below:

Step 1: Perform a clean boot

Note If the computer is connected to a network, network policy settings may prevent you from following these steps. We strongly recommend that you do not use the System Configuration utility to modify the advanced boot options on the computer unless a Microsoft support engineer directs you to do this. Doing this may make the computer unusable.

1. Log on to the computer by using an account that has administrator rights.
2. Click Start, type msconfig.exe in the Start Search box, and then press ENTER to start the System Configuration Utility.

3. On the General tab, click Selective Startup, and then click to clear the Load startup items check box. (The Use Original Boot.ini check box is unavailable.)
4. On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.
   
   Note Following this step lets Microsoft services continue to run. These services include Networking, Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.
5. Click OK, and then click Restart.

Now try to download and install the update manually from KB 963707.

To configure the computer back to normal boot up follow step 2.

Step 2: Reset the computer to start as usual

After you have finished troubleshooting, follow these steps to reset the computer to start as usual:

1. Click StartCollapse this imageExpand this image, type msconfig.exe in the Start Search box, and then press ENTER.Collapse this imageExpand this image
   
   If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
2. On the General tab, click the Normal Startup option, and then click OK.
3. When you are prompted to restart the computer, click Restart.

If the above steps do not fix the problem, please open and copy the last 20 lines of WindowsUpdate.log file from your computer.
