Hi,

I've a file on a external hard drive which I no longer wanted.I want to delete this particular file but I can't delete because of write protection.Then,I found a solution to go registry editor.HotkeyLocalMachine->System->CurrentControl->StorageDevicePolicies i.e in the Write protected.I modified the value from '0' to '1'.It deleted the file but Know I wanted to change the value to back as it was before i.e. '0'.It doesn't effect anymore.I don't want anyone to delete System files or any important files.
Please,Could someone help me out with this solution.That would be really appreciated.
Operating System:-Windows XP MCE -32 Bit.

Thanks
Jack
 

Use the same procedure, change the dword value back to 0.
