ok I will finaly be ready tonight to start with this "project" but I must ask some hotfixes still come with older number but with "v2" so as I understand they were updated recently but still hold old numbering so what happens when I start integrating them and I get KB103 (old, year 2009) KB104 (old, year 2009) KB106-v2 (updated in year 2010) KB109(old, year 2009) do these hotfixes do some checks on integrated file versions or their time compiled because with this sequence logicaly I would overwrite later an updated hotfix with older one that has higher number (under condition that there are few hotfixes that do patch same files) ?
