Item Not Found: Could Not Find This Item

Welcome to Seven Forums numbers. Try a reboot to see if it goes away, or right click the desktop and then click Refresh.

There's a link in my sig for MalwareBytes, Download the free (NOT TRIAL) edition and install and update it. Open the program to the More Tools menu which will bring you to File Assassin, Click Run tool and navigate to the folder to see if that will delete it.

Try Take Ownership Shortcut too and try deleting, if no joy, see the Tip there to allow you full control.

   Warning

Changes made to the Windows registry happen immediately, and no backup is automatically made. Do not edit the Windows registry unless you are confident about doing so.
Microsoft have issued the following warning with respect to the Registry Editor:

"Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to re-install Windows to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk."

How to back up the registry
Before you edit the registry, you should make a backup (i.e.backup the current settings).

1. Open the Registry editor.
2. On the 'Registry' drop-down menu, click 'Export Registry File'.
3. In the Export range panel, click 'All', then save your registry as Backup.
