You asked a question and I can answer, yes is the same Pc.

Is the hard-drive still (showing signs of) failure? 

Have you replaced the hard-drive in the past 10 days?

Is MSE still installed or did you finally manage to uninstall it?

Have any updates successfully installed since last November?

Was KB947821 offered via Windows Update? If not, was there any particular reason you've been attempting to download the System Update Readiness tool?

What are the KB numbers of the other "hotfixes" which have failed to install?

Hard drive has been replaced.

MSE is still installed.

Only thing I find out in the update section is all the updates went through except.

KB947821 failed 7/30/2014 and failed again 7/29/2014 and again 7/18/2014

I get the notice to update windows and then I look to see what updated took place and is always the same hotfix failure but on a different date it failed.

And all hotfix  failures are the same as above.

Assuming Win7 64-bit with Internet Explorer 11 (IE11) installed...
