You could be forgiven for that feeling of deja vu. El Reg is reporting that Microsoft has finally released the first major bug-fix for Vista. But for me the money quote is:

The only problem? A number of security products won’t start up or run on updated desktops thanks to “compatibility problems”.

It would seem that, in the name of security, SP1 breaks other vendor’s anti-virus and firewall products. Needless to say, Microsoft’s own security products are unaffected. Now where have I heard this tale before? Netscape anyone?

Of course, none of this is new. ars technica predicted this assault three years ago when the Redmond behemoth entered the antivirus and antispyware market. The more things change…
