If you want to prank the computer of your friend, you can change the mouse cursor to look like it's stuck and keeps loading.
Are you bored and looking for a way to prank someone else? You can drive him crazy by making him think that his machine is stuck, since he will see his mouse sensor constantly showing that something is loading. The funny thing is, he won't be able to stop it.
Let's see how to do it:
Step 1: Go to Settings > Ease of Access > Mouse Pointer. On the right click on “Additionals settings mouse” and then “Additional mouse options”.
Step 2: In the “Properties: Mouse” window that will appear go to the “Pointer” tab and with the “Normal option” marked press the “Search” button.
Step 3: In the window with all the w pointers do click to “aero_busy.ani” or the two aero below, depending on how big you want your censor to be, and press “Open”.
Step 4: Click "Apply".
You should see that the 'Busy' animated indicator has replaced the 'Normal option' icon.
So the mouse cursor is now a spinning blue loading animation that will never stop.
If you want to go back to the normal configuration, follow the same steps, except that in Step 2, click on the “Use Default” button.
