hi expert,

Once SSH is enabled in Cisco, when we try to access via Putty , in Putty event log, we can see SSH version detail of the Cisco router. Can we disable that not to show to SSH client in Cisco router? I've attached file for you to more understand.

As this discussion shows:
http://www.linuxquestions.org/questions/slackware-14/how-to-hide-openssh-version-331399/

You cannot hide the version negotiation (it has importance); as of putty showing it, again, it is a standard verbosity setting. You can patch putty software though, since it is open source.

Also you may try turning the putty log off completely, or look more into the doc:

What I'm trying to do is in Cisco router. Not in Putty.

Do you have debug turned on for ssh connections in cisco?

Consult this page:

turned on or off doesn't matter. No matter what I set, I still can see SSH version in Putty event log before I log in to device .

Then it is probably non-toggling.
Your last resort would probably be Cisco support, but I don't think they would also be able to help you.

Sorry.
If I may ask, what is the purpose of the version hiding for you?
