Installing lots of software is usually not a terribly destabilizing thing. Sure, there can be bad software out there. It’s usually not the amount of software but the specific software that ends up causing problems after you install it. Obviously, the best approach to saving yourself from those kinds of scenarios is a good backup system.
I try to limit the number of programs I install on my system. It’s a 64-bit Windows 7 system with SP 1 and 12 GB of RAM. I do this because I feel intuitively that the more programs I install, the more quickly Windows reaches that corrupted state that we all know too well, and has to be reinstalled from scratch. I really could make good use of quite a number of programs I don’t have installed but I worry about hastening corruption. I do assume that I can load as many portable applications as I like without worry. Am I on the right track? Or is my thinking just incorrect?
