Broue Master asks: "Nowadays, we need to support not only people at the office, but friends, family, friends of the family, family of the friends... you name it! They all run Windows to a degree and there are many tools to help you when assisting. Personally, I have a thumb-drive with removable memory cards. One of them has a small bootable Linux, the other one is filled with ready to use Windows utilities (CPU-Z, Ultra-Edit32), DOS utilities I've been collecting over the years, and Unix-style utilities (ps.exe, kill.exe, and others) ported to Windows, without the need for a layer like Cygwin. I also have a copy of the install files for AVG, Spybot, Sygate and the likes. But, even though I think I have many great tools, I'm sure I do not know about a lot of great others to help diagnose and solve problem. So I ask you, what's on your thumb-drive?"
