Hi: I'm new to this forum, so I will try and be as descriptive as possible. For some time now, I have noticed that I cannot access my task manager in any way. CTRL+ALT+DEL does not work, and neither does right-clicking on the bottom bar in XP or c:/windows/taskman.exe. I began researching the problem last night and found a very helpful guide (http://www.techspot.com/vb/all/windows/t-27923-Cannot-open-Task-Manager.html) . However, after walking through the detailed steps, I still have the problem, (original content was posted 7/2005). Additionally, I attempted to walk through these suggestions, but to no avail. (ahttp://www.techspot.com/vb/topic47776.html) After running HJT, I removed the items that were explicitly called out, but I'm concerned there may be additional, newer ones I should remove. The log is attached. Additionally, (and I don't know if this is related or not), but I have been receiving an error message immediately when I login every morning. The error message reads, "Application failed to initialize: x800106ba. A problem caused Windows Defender Service to stop...." Research results on this were very limited. Any assistance / guideance you can provide would be greatly appreciated! Thanks.
