Windows 7x64 did a security update and prevented Aion from connecting and causing the freeze(log in screen) how to fix the up dates? note i dont know which update is causing the issue?

Your sentance is internally inconsistent. First you say that it's the result of a security update (you've identified the cause) & then later you say you don't know which update is causing the issue (you don't know the cause). See the problem there? Well, if you think it's a certain security update which is causing the issue, then uninstall/remove it and try again. If you really don't know if the security update is the cause, then maybe it isn't as corelation =/= causation.

i mean the issue happened only after installing the updates ,but i installed 10 of them and i cant specify which one is causing the problem.

Ah, 10 (security) updates is quite different than your original of 'a security update'. Then my comment is still the same. If you really don't know if it's the updates, then maybe it's not....or maybe it is. But you wont know until you remove/uninstall them & try the connection and test installing them one by one to determine if it's one particular one update or the cumulative effect of a few.
