This is the software equivalent of a Swiss Army Knife… on a bootable cdrom.
Here is the url for the website: http://www.hirensbootcd.org/
You can download the ISO image here: http://www.hirensbootcd.org/download/
Burn a few copies and give them to your friends (or Team Members) as cheap but really useful disks.
Go to the bottom of the download page and click on the “See CD Contents” tag. You’ll be amazed at the number of utilities that are there.
