pavel-a / USBWriteProtect1.js

Windows; toggle write protection on inserted USB drives (wsh)

	//-----------------------------------------------------------------------------
	// Toggle write protection on USB drives
	//
	// See http://support.microsoft.com/kb/555443
	// [ HKLM\System\CurrentControlSet\Control\StorageDevicePolicies\WriteProtect: reg_dw: 1 ]
	//
	// NOTES:
	// - This registry hack (KB555443) works only starting from XP SP2; I don't check for the SP.
	// - If a drive is already attached, write enable seems to come in effect immediately;
	// Write disable becomes effective only after the drive is re-attached.
