Creative Cloud Causing Slow Performance

I am a marketing specialist for a high school, and use the Adobe Creative Cloud apps on a regular basis - mostly InDesign, Illustrator, Acrobat, and Photoshop. Over the past month my computer has been running very slow - and I am wondering if it is because Creative Cloud is too much for my computer. Getting everyday tasks completed, even checking email, is a very long and slow process. Adobe Acrobat DC is the slowest app for me to work with - and often times I have to kill the program. I was given an HP ProBook 640 G3 to work on - using Microsoft Windows.I know an iMac is the best platform for Adobe - but currently this is what I have to work with.   I am thinking this was the issue but wanting to get other opinions. Thank you! - Alyssa
