accidently deleted Administrator Account

dear friends
i had deleted my administrator account.but iam not able to recover it.i am running in with windows 8.1
help me to recover it

Were you running the actual normally-hidden Administrator account or a User account with administrative rights? For normal/standard use I've not seen where that hidden account could be easily deleted but I guess if someone works at it they could be successful. It's hidden by default and has to be activated for temporary use then deactivated [probably to protect us from our own foibles].
