[windows] Installing updated versions of unity leaves start menu items under all programs

I noticed that unity keeps start menu items for versions of unity that have been overwritten with updated versions, and doesn't delete the old entries in the start menu when removing the old version during the update.

Here is how that looks after a while:


Does anybody else get this? For now I'm manually erasing them, but what about the uninstall process that happens when your updating versions, if it instead removed that particular entry of the old version when it runs (I wouldn't have it erase all entries, because I do keep multiple versions of unity that I actually use on different projects)...

I'm on Windows 7.

 

The same problem.
