Windows 7 - Windows update stuck at 0kb 0%

​Hi,

Thank you for posting in Microsoft community!

You've reached the right forum for your question. As I understand, you receive error Windows update stuck at 0%.

1. Did you make any changes on the computer prior to the issue?
2. Which update are you trying to download?
3. Where are you trying to download the update from?
4. Which anti-virus software is installed on the computer?

Method 2:

Some times security software installed on the computer conflicts with the downloading and installation of updates on the computer.

NOTE: Antivirus software can help protect the computer against viruses and other security threats. In most cases, you shouldn't disable the antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

Method 3:

You may download & install the updates manually from the Microsoft Download Center.

Please reply with the results. I would be glad to assist you further.

This worked, except I didn't have to do a restart.  It must have been able to kill whatever service was blocking windows updates from downloading.

This problem often arise with the windows 7 . the reason is cancelling the windows update during the process or force stop the process. 

Your Windows is actually downloading the update but the status bar is not showing so thats what lead to the confusion. Connect your windows with the fast internet connection and wait. It will be completed itself. Dont worry.

UPDATE UNABLE TO INSTALL.

Sorry, it did not work for me. thanks, anyway.
