all know the prop, an fresh operating system without installed programs run fast, clean and stable
3 months later slow, 6 months later all sucks and need an refresh
the biggest reason known too, you installed too much useless shit
easy proposal, the most sofware you need can use as an portable application
and allmost for free
i avail oneself only installprogs they need the registry for working well, like antivir/firewall/codecs (this programs cant made portable)
i favorite here:

most programs with an unistaller routine you can made portable with an trick
copy from your install folder and paste in an other one
the big drawback are, an newer one like an update need an fresh install
the easyer way are using an professionell portable software from your developer
but the most commerciel software are installware
iam an freeware fan and here my collection favorites
