"And withing my organization currently running apprx 75 CISCO switches. now should I configure above setting in all switches or else those switches which i want to make dual uplink."
Generally you should run some STP variant even when you don't have intentional L2 loops in your topology (this to block unintentional L2 loops).
One issue, though, running STP everywhere, it often much delays edge clients (e.g. user PCs) from quickly (or possibly even [due to giving up waiting for a DHCP IP address]) connecting to your network. On, at least Enterprise grade Cisco switches, this problem is addressed by using "port fast" on such ports.
Again, if devices offers it, a rapid-STP variant should be used.
"Can you please share its CLI !!"
I would need to know exactly switch model(s) and IOS version(s).
I did see in your one posting mention of using SG300 and some version information.
I not familiar with Cisco's SMB switches and routers, but I would hope the reference link @balaji.bandi provided, or the diagram with STP interface costs, @MHM Cisco World provided, may lead you to the particular information you need.
If not, let us all know.
