Vista Error Code 0×80240016 While Updating Windows Defender may be a Skype Problem
This error code 0×80240016 happened to me while I tried to update Windows Defender. After some searching I found that it may be a problem with Skype and its associated plugins for Firefox and IE. When I clicked on the windows defender update icon in the lower right of the screen vista admin did not popup and ask if I wanted to OK this.. Only after I disabled the Skype plugin for Firefox then clicked on the lower right screen icon in the tray that the admin screen appeared then I clicked approve and windows defender updated with no problem.
Maybe I just got lucky, but I hope this might help other people with the error code 0×80240016 problem. This may be an Access Denied. Meaning You do not have sufficient permissions. Be sure you are logged on as an Administrator. I was already logged on as admin but it did not let me update the first time but it did the second time. If anyone else was able to fix the 0×80240016 error code problem please post a comment.
Other possible fixes to this are:
Reboot (log on as admin)
Try Updating again.
Uninstall Skype

Yes i saw that page to but i did not need to do any of that.. But thanks for the link and the help.
Unfortunately Skype is the cause of more problems. WampServer can’t start its services when Skype is running, for example. I now only start Skype when I really need to use it and kill it when I don’t (I also don’t have it start up automatically when I start windows).
