The new Windows Live Messenger features the new My Sharing Folders which enables you to share files with your contacts.
Even if you’re not using it and the feature is being turned off, you will still see the “My Sharing Folders” icon in your My Computer and Explorer.

To remove the My Sharing Folders from My Computer and Explorer…


First, you need to check what version of Windows Live Messenger are you using.
Run Windows Live Messenger, go to Help -> About Messenger and you should see an info box like the image below.

I have Windows Live Messenger version 8.0.0812.00.

I need to paste the command line below to Start -> Run and click on OK button (Refer image below)
regsvr32 -u “%PROGRAMFILES%\MSN Messenger\fsshext.8.0.0812.00.dll

If you got it right, you’ll get a confirmation box saying “DllUnregisterServer in C:\Program Files\MSN Messenger\fsshext.8.0.0812.00.dll succeeded.”

Important Note: If you have other versions of Windows Live Messenger such as 8.0.0787.00, you’ll need to change the command line in order to successfully unregister the fsshext dll. For example, if you have version 8.0.0787.00, the end of your command line would be fsshext.8.0.0787.00.dll instead of fsshext.8.0.0812.00.dll

Good luck!
