Users can speed up windows by performing some tweaks like disabling the operating system’s file indexing service, cleaning up prefetch, cache and temporary files, installing some RAM, removing unused applications, fonts and files and getting a reliable antivirus that is capable of cleaning the computer. If the computer is running 128 megabytes or 256 megabytes of RAM, it would be better to upgrade to at least 512 megabytes. In spite the fact that it will cost users some money, this suggestion will best enhance the performance of the computer. Defragging the computer’s hard disk drive can also speed up Windows.
