Start up took much time

If you want the computer to start faster, you need to reduce the number of programs and services that the computer automatically runs at startup. Or possibly increase the amount of RAM installed (if possible). If your hard disk is severely fragmented, defragging can help speed things up a little bit. If the system is paging excessively (or worse yet, constantly adjusting the size of the paging file(s)), you can reconfigure these options. If your system has enough memory, you can change settings so the executive never gets paged out (must have at least 512MB of RAM to do this). There are literally dozens of ways to speed up a system, but you need to know where the system is faltering the most. On most systems it has to do with automatically loaded services and startup programs. Uninstall any software that you never use. Set little used services to Delayed Start. Use the msconfig tool to stop programs that you don't use from starting up on boot.
