I have spent considerable time in testing each software included in this list, and they were able to bring some level of speed improvement for me. Some do it better than others, while some are focused on specific aspects only. The software that are really good at speeding up PC take care of most of the aspects mentioned above. Then there are some application level tweaks also involved, especially for web browsers, that involve cleaning temp files, removing unnecessary toolbars and extensions, and some more tweaks. All the above tweaks are PC level, and improve performance of entire PC. Registry also needs to be optimized to remove junk entries, and useless programs need to be uninstalled. Then RAM management is another aspect (though, it is a pretty debatabale topic, as Windows itself does a pretty good job at managing RAM). Next is the hard disk itself it should be free of temp files, and should not be fragmented. Next you need to see that Startup sequence does not have unnecessary programs starting up, that would increase the startup time. To start with, you need to ensure that no unnecessary processes are running in the background that would take up the RAM and processing power that your other programs need. PC Speed up itself is a very subjective process, and involves fixing lot of things on the PC.

There are too many software out there that claim they can speed up the PC, but not a lot of them are really good at that. Here is a list of best free software to Speed Up Computer.
