Devin has noticed that his computer now takes much longer to start up than it used to and runs almost every program a bit slower than he feels it should. What is a likely cause of his problem?

A. System is not updated

B. He is missing a patch for this operating system

C. Data has not been backed up recently

D. Too many programs running at start up

The answer is D) Too many programs running at start up

By default, a computer runs several apps as soon as it boots. However, running too many programs on startup can slow down your computer. These programs will continue running in the background of your computer and will result to the computer running slowly.

You can use the task manager to stop currently running applications or completely disable programs which are automatically launched upon boot up.
