I used to use basic configuration 2GB ram for my laptop with windows 7. I ran into trouble when I needed to use multiple windows open (started swapping to hdd whenever switch occured), and cleanmem helped me a lot by giving me few more precious memory available (although admittedly new operation required same swapping, switch between open windows became much smoother).
now I finished long wished upgrade to 4gb ram. do you advise to remove cleanmem at this amount of memory?
