Parallel installation tool is a nightmare, it add a bunch of Mac Application short-cut which I don’t see any useful into the Windows VM machine. If you ever run uninstall Parallel, they won’t go away.

You will need to go to the following location to remove them manually:

• C:\Users\${USERNAME}\AppData\Roaming\Parallels\Shared Applications
• C:\Users\${USERNAME}\AppData\Roaming\Microsoft\Windows\Start Menu

If your Windows have multiple user account, you might need to go to all user folder to remove them one by one.

Parallel, I’m done with you.
