Just wanted to share this with everyone in case you overlook this feature in Windows. My one system was running low on free Hard Drive space and I saw that Windows 10 was almost 50GB in size. I went looking to see what I can get rid of that might not be necessary and found the Disk Cleanup utility built into Windows 10 and with everything checked including system files, I was able to get 23GB of space back.
Checked on my Windows 7 system and found that 14GB of space was able to be freed up on that which gave me back some of my SSD space.
So figured I'd share here so that people get a reminder of a utility they can use to get drive space back, whether your running low on space like I was or just want to do some trash cleanup in the system getting rid of what may not be necessary. You can check and uncheck boxes to what you want to delete and keep. I deleted everything i could shed because no important data to keep from those locations on my system.
