I have the exact same setup. This worked for
me (for the Arduino ISP programmer on COM3):


     avrdude -pm328p -P\\.\COM3 -carduino -b19200 -U flash:w:uno.hex -U 
eeprom:w:uno.eep.hex -U efuse:w:0xfd:m -U hfuse:w:0xd9:m -U 
lfuse:w:0xff:m -v


Make sure you are actually using a more recent version of AVRDUDE (the 
version that comes with

more recently versions of the Arduino IDE is OK). Some other installed 
software may have placed an

outdated version of AVRDUDE that is started instead, due to the content 
of the "PATH" environment

variable. I once positively found I had to use at least version 6.1 of 
AVRDUDE (both the older ones

that came with a version of AVR-GCC and with Arduino IDE v. 1.0.5 (v. 
5.11) were too old).
