Hello,
Thank you for posting your query on Microsoft Community.
With the issue description, I understand that you are getting a pop up to install an update regarding Adobe Photoshop Elements 13 everyday on Windows
8.1 machine. I would appreciate if you could help me with more information:
1. What is the exact message that is popping up on your computer screen?
2. Is the message popping up through Windows updates?
I would like to inform you that in order to diagnose the issue, we need to check and ensure whether the message is coming from an
authentic source. Because there might be a possibility that some virus is trying to get into your PC or this might be a genuine update which has not been installed or configured appropriately. Therefore, it is popping up repeatedly.
I would recommend you to include a screenshot of the issue to help us understand the problem and provide appropriate solution steps.
Here is how to include a screenshot in your post
