How to remove Windows messenger

Step 1: Navigate to C:\WINDOWS\inf and look for the file named sysoc.inf (NOT sysoc.PNF !), Copy it to a secure location on the hard drive to back it up. Remember to always back up befor making any tweaks or mofifications to Windows.

Step 2: Now we get to the diry work. Open sysoc.inf an look for the following line in the [Components] section:

msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,hide,7

Remove “hide” so that the commas sit next to one another. This is what it should look like now:

msmsgs=msgrocm.dll,OcEntry,msmsgs.inf,,7

And you’re done editing! Save the file and quit.

Step 3: Go to Start -> Control Panel -> Add or Remove Programs -> Add / Remove Windows Components and you should see “Windows Messenger” on the list. Check the box next to it to remove it.
Note: you can remove other Windows programs the same way, but as always, only at your own risk.
