HBCD can be considered a valuable tool[2] for use in troubleshooting and recovery of computers. As it is bootable, the operating system of the computer need not be available for the tools to be usable. All that is required is that the computer is able to run Microsoft Windows and Linux (but it does not have to have either of these installed at the time of use). Most of the tools are also available when the operating system is already started. Crazy Tronics Special Bundle: EXTRA BONUS SOFTWARE INCLUDED TO OPTIMIZE YOUR PC TO RUN AT ITS BEST!
