I had the same issue. When I uninstalled vmware converter, it left a lot of things behind. One thing I did was run CCleaner by piriform a couple of times to delete the old registry values. You can download ccleaner from piriform.com/ccleaner, and when it is installed, run it as an administrator and select the registry tab. Hit the scan for issues button, and select the issues relating to vmware. Make sure you know exactly what you will be doing... don't select any issues that you don't understand, or don't pertain to the uninstalled vmware software.
press the fix selected issues... button and when prompted back up your registry, just in case (:
If this didn't fix the issue, then another thing you can do is check the local users and groups on your computer.
- Press the Windows key + X
- select Computer management, and enter your administrator password when prompted.
- When the computer management window comes up, select **Local Users and Groups,**on the sidebar
- double click Users
- VMware_conv_SA or something similar should be listed as one of the users for your computer. (dont worry about this, vmware isnt spying on you. they use this user account to run their conversion services while the computer is not logged on to a user account)
Only do the following if you are positive that you want to remove all traces of VMware converter from your computer
- Select the VMware_conv_SA user and press the delete key on your keyboard.
- Reboot
Go back to windows explorer and try to share something. VMware_conv_SA should not be listed.
