I tidied up my Start menu a while back, organised it into folders and removed programs I do not access. This was also around the time I changed the location of my My Documents/Desktop etc folders via the Location tab of the directory properties (bought an SSD, so moved those folders to a HDD).
Now I'm finding applications (such as the Office suite) are installing their Start menu shortcuts to a directory named "test" on my desktop. These shortcuts don't show up in the Start menu.
I don't even know where to start looking to troubleshoot this. I have noticed that renaming this "test" directory requires administrator permissions. I'm not so much worried about the shortcuts not showing up in the Start menu - I can just move the shortcuts to the correct folder - as I am about the pesky, mysterious test folder on my desktop.
