Under Vista the task manager feature is not automatically launched upon pressing ALT+CTRL+DEL. Results: you shall get a splash screen with various options, from which you must select the desired option. The process is as lenghty as the text I've written above! ..
Still there's a way to access the Task manager more rapidly, you can create a desktop shortcut, here's how:Right Click on an empty area of the Desktop>Select New>Shorcut
Enter the following path (location of the item):
- Click on Next
- You can give a custom name to the shortcut or leave it as "taskmgr".
Click on the finish button and it should be OK.
you can still use the "taskmgr" command in the Run tab or the Windows search bar for quicker access!
