Hi! I just did a fresh install of windows 10 pro last week. Everything is working great. I'm running an AMD A10-5800K, a seagate st500dmo 02 hard drive, and an asus f2a55-m lk motherboard. After 3 days, I checked the properties of my drive, and instead of 19gb it showed 49 gb used. I checked the size of all my files and directories, but I can't account for the extra 30 gb. I have avast essential one anti-virus and malwarebytes. I did a micro trend housecall scan, and I was clean. Where did the extra 30 gbs come from? I haven't done a windows update yet, and have a lot of files waiting to be installed. Could that be where the 30gb is? Any and all responses will be greatly appreciated. Thanks.
