How can you maintain your system?

my system is maintained using the system tools in start menu. there's some tools for maintain. mainly the system restore and backup, disk cleanup, task scheduler, disk defragmenter, control panel and so on. the itself point out the tasks. from those necessary tasks in every month. thanks

To maintain the flow of your system you should use a registry cleaner program, a temporary files cleaner program and an Automatic or manual Defragmentating program. And more or less try to have the newest versions of programs, might increase speed or fix bugs, and definitively the newest drivers.If you'll search you'll find very good programs that are also free, for example I use CCleaner, a very good free program for Cleaning temporary files and registry, for Defragmentation you could use Auslogics Disk Defrag, another free and good program.
