Note to all people trying to trick Messenger into not upgrading:
I'm the first person to acknowledge that Windows Live Messenger got bigger and that not everybody 'likes' it (I didn't liked the look at first either, believe me). But,
instead of trying to trick Messenger, please upgrade for your own safety and for the safety of others....
So, I know some of you do not like the look or whatever of Windows Live Messenger 2009. But the fact is that you will cause problems for yourself and others by tricking Messenger and trying to avoid the upgrade.
There is actually no reason why you should not update... except for the looks maybe (but that can be altered with Plus! skinning). Moreover, not updating means that
you will be vulnerable to possible bugs, and even worse, security issues.
The latest version of Messenger fixes again some security issues and bugs. It _is_ also a lot more stable than MSN Messenger was, eventhough you think it is not. If you have problems with the latest version it is not because it is full of bugs, but most likely because there is another issue at hand here which didn't popped up yet, which you didn't noticed before.
Eg: you previously tried to alter some files of Messenger and forgot about it. Or you previsouly had problems, surfed the web and found a fix, but when you tried it nothing happened, so no harm one right, wrong, it now backfires...
And if there are bugs in the latest version (of course there are always some bugs), then it would be imperative that you report them so they can be fixed properly, instead of trying all kinds of tricks which you find on various (unofficial) sites on the web.
Sticking your head in the sand and trying to trick Messenger is not going to fix such bugs... on the contrary, you are actually making it harder for Microsoft to fix possible bugs if you patch Messenger!!
The reason is quite simple: since you have patched the version number (most used method), the servers recieves protocol messages which do not belong to that version for example. Thus making it harder for MS to pinpoint potential connection and protocol problems/bugs/security issues.
Also, you're not only making it harder for Microsoft to fix and/or update possible bugs in the protocol and in the program, you also _will_ experience problems yourself in the long run with for example: signing in, contact syncronizations, adding contacts, and what not.
Because you have patched Messenger there is a very good chance that support will not be able to help you either.
Also, some tools, updates, etc of other software (based upon Messenger) will not work anymore or be crippled too.
So, in the end, you are all making it yourself (and other people) harder.
And insisting in using an older version only means that you are now wide open for possible security attacks.
