But many of the customers are posting in salesforce community and also in Salesforce Idea that they don't want to create Task also when converting the Lead to Account.

I thought that by writing code or creating custom page will give solution to the problem.
But the answer is so simple, I believe this will give solution to the users

Just follow this simple steps..

Click YourName-->setup-->Customize-->Activities-->Task Page layout
Then Click Edit to the Page Layout, now Pagelayout window will appear as shown in the screenshot

Move mouse pointer to the Subject field,now wrench icon will appear click that to edit the subject field properties.
Then disable the Required check box and click save and close.

Now Convert the Lead into Account without entering the task details

Note:-
We can't make the changes for Status and Priority, even though it is required field it won't create task when converting the Lead

I believe this gives solution to following IDEA
