Hi Alan,
I see that you have followed some suggestions from the previous thread.
I would sugget you to follow these methods and check if it helps.
Method 1:
As you are not able to start Windows Search Service, you would have to check the Dependency service.
To do this, follow these steps.
a.Press Windows key + R on the keyboard.
b.Type services.msc and press OK.
c.Scroll and find Windows Media Player Networking Sharing Service.
d.Right-click and select Properties.
e.Set the Startup type and set it as Automatic.
f.Click Start to start the service.
Now, try to start the Windows Search Service.
**Method 2:**If that does not help, I would suggest you to run an System File Checker (SFC) scan and check if it helps.
Use the System File Checker tool to repair missing or corrupted system fileshttp://support.microsoft.com/kb/929833/en-us
