Getting the "Device has problem: 0x0a: CM_PROB_FAILED_START." error code 10 while installing device driver for Arduino Uno
Error code 10 mean Bad Environment.  I would guess that you are using the wrong driver, probably 64 bit on a 32 bit OS, etc. 

This does not look like a Arduino fault, it looks like a windows Driver fault, so unlplug the board, reboot the PC logon as admin and download the latest drivers for you device and see if that fixes it.  You might be able to get better help on a Windows admin forum I think.
