|Windows update error|
First you need to check the Windows update services if they are running.
To check for Windows update services, select the start button and type on the search box "services". Or you can go to run and type "services.msc". Either the two, it will open up the Windows services menu.
Next, look for the BITS, Windows Update, and Cryptographic. All these services should be set to automatic. If for some reason there's a component that's currently in disable status, them just right click on it and click automatic.
After finding these services, restart them all by doing a right click on the services icon and select restart.
Another thing is deleting temporary and junk files on the Windows update folder.
To do that, go to Computer -> C drive -> Windows Folder -> Software distribution folder -> data store -> delete all files in this folder, also delete all the files in the downloads folder.
Go to Microsoft website and search for "Windows Update Agent" or simply click this link Microsoft Windows Update. Make sure you have the latest Windows update agent. If not download the latest Windows update agent, and make sure you download the either 32 or 64 bit depending on your computer.
Lastly, download the Microsoft fixit tools by going to http://microsoft.com/ and look for the Windows update fixit tool.
