How to Access the Task Manager Faster

Most persons use Ctrl+Alt+Del to bring up the lock screen from where they'll be able to choose the Task Manager, but if you're about speed as much as I am then you would love this neat trick:
use Ctrl+Shift+Esc instead and cut out the 'middle man'.

BTW: The Task Manager is a Windows feature/utility that gives you information on the programs and processes that are running on your computer.  You can use the Task Manager to close an unresponsive program or to monitor which program(s) is hogging your system resources (memory) or getting all your CPU's attention.

Avoiding installation of unwanted programs

Many software companies and developers these days are including add-on software in their bundles which in most cases are unwanted by users (including myself) since they can lead to your computer slowing down either at Start-up or Shutdown.

To avoid accidentally installing these unwanted programs/toolbars/add-ons etc. ALWAYS use the 'CUSTOM install' option once it is available and READ carefully what you are saying YES or ACCEPT to especially if the software you're installing is FREEWARE or SHAREWARE
