Hi Harry,
I would like to have more information about this issue. You have mentioned that the Windows Update issue had started recently, so, what are the recent changes that you have made to the computer prior to the issue that you had initially with Windows Update. Also please answer to these questions:
1) Do you get any error message/code when you try to launch Windows Update? If yes, what is it?
2) Do you have any third party security program installed on the computer?
You have also mentioned that the support engineer from Microsoft who was working on your computer, stopped the command line tool which scanned for the corrupted system files, in between. From this description, I think he was performing an SFC Scan and after which you are unable to launch Windows Update to check and run the pending updates. It also shows in “Services” console and in “Task Manager” that the windows update service has stopped. So, let us first reset the Windows Update Components and check if the resolves the issue.
Method 1:Manually Reset Windows Update Components
a) Press “Windows Logo” + “X” keys on the keyboard and then select “Command Prompt (Admin)” from the menu.
b) Copy the following commands and then right click in the Command Prompt window and select “Paste” to paste all the commands in it.
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
c) Please wait for the process to complete and then press “Enter”.
d) Type “Exit” in the Command Prompt to close it.
Now, run the Windows Update and check if it installs all the pending updates. There are also possibilities that something might have happened when the SFC Scan was stopped in between while it was repairing/recovering the corrupted system files. So, let’s try that again and check the result. You may need to use the Windows 8 installation disk for the SFC Scan to recover the corrupted system files.
Method 2: Run an SFC Scan
The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.
a) Press “Windows Logo” + “X” keys on the keyboard and select “Command Prompt (Admin)” from that menu.
b) On the command prompt window, type the following command, and then press “Enter”
sfc /scannow
c) Follow the on-screen instructions and complete the scan.
Important: It may ask for windows installation DVD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.
Now, run the Windows Updates and check if that resolves the issue. Please do get back to us with the results. If the issue persists, we’ll be glad to assist you further.
