Just installing software doesn't matter at all. You can install quite a lot of software on a 1 TB disk. But you can't run all if it at the same time. The less you run, the less RAM and virtual memory is used.
Is there a limit you should respect to the amount of software you have on your computer? when is too many?
Am I right in guessing, the determining factor is your ram and cpu % being used at Windows boot-up?
I'm at 58 process 5% cpu 37% memory
Or is there other factors to consider (too much clutter in the registry)
