Create a new account with administrative rights, login with new account and then delete the one you want by going into Control Panel>User Accounts.

Awesome It helped. Time to time it happend have little "brain fart"....just don't figure out such simple thing. Thanks a lot. Have great day

You can also do it without creating a new account.

Seavixen32 Unfortunately this didn't work for me.....it still retain old/initial name what I've input while first starting the Acer notbook. Thanks for response anyway.

Glad it worked out for you.
