I think we've talked about this little program before: The PC Decrapifier.
For 'cleaning up' a newly bought Win PC.
I don't have a lot to do with 'Windows' these days, just looking at my family members Comps it's quite intriguing, how each has their setup.
One Sister has no third party software at all. It's bleak. She just basically uses IE, and Outlook, an MS Email and organiser thingo. That's what she wants, sensible.
Another member of my family has expensive third party Pro versions of Photoshop, Real Player, Adobe Reader, I could rattle on. They believe if you don't pay, it can't be any good.
A lovely thing about Linux is not having a Registry; although if you are stuck having to use Windows it's the place to be for tweaking, and backups.
Finding and installing Hardware Drivers can be made less painful by buying a Driver backup program, but really probably only necessary if you have a Network and are the Admin in a paid position.
Again; kind of a personal thing isn't it. If you repair Comps and have regular customers having a backup of their drivers can save you heaps of time. I think a lot of Techs just install windows and leave third party stuff up to the client to deal with. Time is money.
There is a CLI in Windows, too, btw. I just don't know all the commands and how powerful the default cli is...
My Uncle who was a programmer way back in the 70's calls today's MS Dos, "Mickey Mouse Dos."
You can do quite a lot with it still though, well in XP I used to...
