Instead of starting with GUI, you start bitcoind from command line.
Another approach is using pywallet on windows.

You can get the private key of a single address in the standard bitcoin-qt client by going to help->debug window->console. You can then type in "dumpprivkey" without quotes followed by the bitcoin address you want the private key of. Hit enter and the string it shows is the private key for that address.

Be careful with who you give this to, because with it someone can take all the coins currently associated with that address. Hope this helps.

thanks guys , sorry if i sound stupid Uncurlhalo but where do i type   'help->debug window->console'  .....in the command line??

and do i have to open bitcoind in command line first and if so how do i do that ........when i try to open using bitcoind -daemon it says ....'bitcoind is not recognized as an internal or external command, operable program or batch file ' ?
thanks for your patience guys
