Best way to solve this problem without re-installing the Operating System
Just do the task in given sequence:
Open Application> Utilities> Disk Utility> Select Macintosh HD> First Aid> Verify Disk Permissions> (when done) Repair Disk Permissions
Restart your system
Try pasting this command into Terminal (be careful not to select any extra space either at the beginning or end of the command):
mv ~/Library/Preferences/com.apple.finder.plist ~/Desktop
Press 'Return', then restart the computer.
If this works, you can delete the file that appears on the Desktop. Notice that you may need to reset some of your Finder preferences.
If it doesn't work, do not delete the file that appears on the Desktop. Instead, return the file to where it came from and restore all your Finder prefs by pasting this command into Terminal:
mv ~/Desktop/com.apple.finder.plist ~/Library/Preferences
Then press 'Return' and restart the computer.
Let me just get this right:
1. You ran this command in Terminal and pressed return
mv ~/Library/Saved\ Application\ State/com.apple.finder.savedState ~/Desktop
2. Closed all Finder windows
3. Restarted the computer
and then a Finder window was already automatically opened on restart? That doesn't sound possible!
Can you try this, without restarting the computer:
1. Close all Finder windows.
2. In terminal, paste or type this (*note: if you type it, make sure 'Finder' is capitalized, i.e, not 'finder')
Then press 'Return'.
Does the problem window re-open on the desktop or not?

From this post:
Before I restarted the finder was closed but still had a dot in the dock. The finder is alway running and cannot be shut down, is this correct?
I'm not sure at all if OP is still talking about an actual open window or just the fact the there is the triangle under the Finder icon in the dock........
Out of curiosity: why is it that you have no applications in your Applications folder? Instead, I see Mac OS in the Applications folder and it seems to contain what your System folder should have. Here is a screenshot of my Applications folder:
It appears you changed the file hierarchy of the OS which is not really recommended.
