I have found another bug regarding the startup tool on Win 64 bit machines, in my case Win7, but this happens in Vista 64 as well.
When installing Live Messenger, a tool called Windows Live Call also gets installed.
When I try to disable it from startup(msgrdvmn.exe), it is turned on again upon restart.
So I checked msconfig, and there it shows 2 instances of that service that needs to be disabled.
I also checked with Ace Utilities in their startup manager module, and there it also shows 2 instances.
So disabling both of them works.
Can you take a look at it and fix it please so it shows both instances in Ccleaner as well?
