The DWORD (32-bit) and QWORD (64-bit) values do not depend on your Windows version. You can find any of these values on either a 32-bit or 64-bit system.
It is therefore normal to have a 32-bit value in the registry of your 64-bit computer.
Thanks for the info HelpiOS, but even after making use of dword (32 bit) I am not able to format my SD card.I have tried out every method on internet ????.Well do you have any different ideas?
