I, and many other previous Windows users notice that the computer seems to get progressively slower over time. I bought a leapfrog crammer only to find it installed process that sat there waiting for me to plug the crammer in so it could run the software. It took up three percent of the CPU twenty-four seven, seven day a week! This is one of the main reasons I left Windows. But, Ubuntu doesn't seem to slow down over time at all. Does Ubuntu allow programs to install background programs like the leapfrog crammer did to sit there like a leech and suck away at resources? Could someone explain why Windows tends to get slower over time, and is Ubuntu vulnrable to this too? Thanks for any help, this is puzzling me.
