Hi. I just wanted to thank you. I was having the same error code with KB2267602. The directions that you gave worked perfectly:

**Make sure Windows Update and Background Intelligent Transfer services are available and running.

Click Start, type services.msc in the Start Search text area, and then click services.msc in the programs list. If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.

Double-click Background Intelligent Transfer Service.
If the Startup status lists Stopped, click Start and then click OK. If the status is Running, right click then select Restart

Double-click Windows Update.
If the Startup status lists Stopped, click Start and then click OK. If the status is Running, right click then select Restart

Once I restarted "Background Intelligent Transfer Service and Windows Update, the problem was solved. The security update installed.

I tried the Windows Update Troubleshooter, but that didn't work. So I tried the services.msc next.

I really appreciate the tips you shared!
