What's an easy way to lock my desktop?

Q:
What's an easy way to lock my desktop?

A:
If you want to lock your desktop (that is, take it back to its original start up mode, where you must enter your password or click to enter), there's an easy way to create an icon just for that.
Do the following to avoid using any other key combinations in the future:
Begin by right-clicking an empty spot on your desktop, point to New and click Shortcut.

In the Create Shortcut dialog box, type the following in the “Type the location of the item” text box:
“rundll32 user32.dll,LockWorkStation” (remove the quotes when typing)

Click Next.
In the “Type a name for this shortcut” text box, type “Lock” (or whatever you'd like to name it) and click Finish.

Now, your desktop will be locked whenever you double click on the new icon you just created!
