So, I'm a tech who does a small amount of on-site service, usually for either individuals or small businesses and almost always on Windows XP or Vista machines (though I occasionally see 98 Second Edition or 2000), and I'm looking for things to add to the list of software I bring with me. Also, I generally try to keep it all in the free to very inexpensive range. Here's what I carry around at present:
Burn In Test
HijackThis (which kinda scares me, so I never use it)
Spybot - Search and Destroy
Windows Installer Cleanup
... and a copy of the Windows Defender installer.
I have a fair amount of software in the malware/spyware removal realm, but not much in the way of hardware or registry diagnostics. So, what more should I be bringing with me? (I was inspired to ask over the course of this thread
and have been looking over some of the other stuff there, like Combofix.)
