Here is my issue:
When I boot my computer up, and login (using classic login, not the welcome screen), the monitor is black. It's not in standby, it's receiving signal, but it's just black. If I press CTRL+ALT+DEL, the Windows Security window appears with the Change Password, Task Manager, etc. buttons. It looks normal. I can click on the Task Manager button, and start new tasks. However, the Start button/task bar aren't there... the window of say, Firefox, completely maximizes to the size of the screen. If I end process explorer.exe and restart it, nothing changes. However, if I log off (not reboot) and login again, sometimes it takes a few times, it will startup as normal.
I've recently installed some programs that I didn't end up keeping installed -- I uninstalled them again. One in particular, FolderLock (I believe that's the name) trial, messes with the registry to hide selected files from explorer, etc. It didn't seem to uninstall completely, but I can't be 100% sure that's the problem. I was getting errors when I closed Notepad and a few other programs, though not most programs. I ran a registry fixing utility/program that appeared to fix that. However, whenever I "Shutdown", the error windows appear for a few processes briefly, not long enough to read, before it goes into the light blue screen/"Windows is saving your settings" etc.
I just completed a scan with RootKitReveal and here are the results too (I'm not sure what they mean):

I considered posting in the malware forum, and if this problem is more appropriate there, feel free to move the topic. However, all of my antivirus scans, etc. come up fine and it appears to be something with the registry, though I don't know where to begin. I've already tried System Restore, to no effect. Could someone please help?
