I found the solution to this same problem that I suffered from, until now. I am on Windows 7 Ultimate 32bit.
Right-click the shortcut icon. Go to Properties. Go to tab Compatibility. Section 'Privilege Level' has a tick for "Run this program as an administrator", even though Properties, Shortcut, Advanced is unticked for "Run as administrator". (This must be a Windows feature:-) This tick for "Run this program as an administrator" is greyed out. Click on the button below it <Change settings for all users>. Now the tick can be cleared, and your standard account will get cleaned.
I would not have found it without the prior conversations, so thanks for the contributions! Hope this works for you too!
