Can any one tell what affect can hapen to SQL Active Active cluster After Windows Security patching.
Windows team are going to update the security patch on our Active Active cluster. Do i need to bring the node offline before the patching. or i can stop the service of SQL service. Do Stoping the Sql server will not affect the fail over .

You mention Active/Active cluster, by this I presume that you are running two SQL instances on a two node cluster. If this is the case here are the steps I recommend for patching Windows:

Personally, I'd take the node offline for patching like this. Also, I'd make sure I had a good backup in place before hand (good = tested recovery). Depending on how you stop SQL Server, it can cause a failover, so be sure you use the Cluster Manager software to stop the service if that's what you're going to do.
