Use your mouse to right-click an open area in the task bar and in the context list select Task Manager
or go to Start > Run and type: taskmgr
Click OK or press Enter.
When Task Manager opens, select the "Processes
" tab and you can view what is running.
You may have too many applications loading at startup
when Windows boots. Almost all applications you install want to startup when Windows loads. If you allow all these startups, they will compete for and use system resources resulting in poor performance and a slow system. Many of these programs are not needed and disabling them can save resources and improve performance as they can be accessed from Start > Programs or an icon on the desktop if needed. Other reasons for slowness include disk fragmentation, disk errors, corrupt system files, unnecessary services running, too many browser Add-ons/toolbars, failure to clear browser cache, not enough RAM, dirty hardware components, etc. Incompatible browser extensions and add-ons can impact system performance and cause compatibility issues such as application hangs (freezing).
To disable unnecessary startups, use a free Startup Manager
like one of the following:
You will be provided with a list of programs that load when Windows starts. If you untick an entry it will no longer run at startup. This will allow you to experiment and see how your system performs with any of them disabled.-- Note: some startup programs are necessary so be careful what you disable.
If you are unsure what any of the program entries are or if they are safe to disable, search the name using Google <- click here for an example
Or search the following databases:
