If you want to really know what's going on in your PC, this toolkit is for you. I have found that over the years, many of these tools are indispensable. (Thankfully I haven't needed them for anything very serious!) Some items require a fair amount of PC knowledge and all of them require using them with care. But they are free and very powerful! (IMO, Russinovich is a genius!)

I've had Autoruns on every computer I've owned for years. One of the best and most useful little programs around.

Agreed! I used PSEXEC on a daily basis.
