Using a laptop running Windows Vista, when trying to change my startup programs, I get a message saying, "Windows Defender is turned off" that won't let me change the programs until I click "Turn on and open Windows Defender." When I try to turn it on, I get an error message "Windows Defender encountered an error 0x800106ba. A problem caused this program's service to stop. To restart the service, restart your computer or search Help and Support for how to start a service manually."
I tried using the information from this page} (http://support.microsoft.com/kb/931849), but none of the steps have worked.
NOTE: My error message is neither of the ones listed on that page, but the number is the same.
Step 1: I did, but I still get the error message.
Step 2: Windows Defender is not in my list of programs to uninstall, but it is listed in the start menu. I still tried reinstalling it but got the message, "You do not need to install this software because Windows Defender is included in Windows Vista. You can access Windows Defender from the Security section of the Windows Control Panel."
Step 3: Again, Windows Defender is not in my list of programs to uninstall. I tried skipping to d (using the Windows Installer CleanUp utility) but when I search for "programs and features" there are absolutely no results.
Step 4: The first two file names succeeded, but at the third one it tells me "The module wucltui.dll failed to load.... The specified module could not be found." Fourth works, but wuweb.dll doesn't. The next few work until I get to initpki.dll, and the last one does work.
I restarted the computer in the hope that something might have changed, but to no avail. Any advice?
NOTE: From reading other posts, it seems that most people get this message every time they turn on the computer, but I never get it unless I try to turn it on manually.
