System files taking up 170 GB on a brand new computer

Hi,


I just got a new computer today. It came with Windows pre-installed (but not set up). After setting up, I updated the OS and installed three or four programs (Steam, Spotify, Chrome, and one video game that takes up about 13 gigs).


I noticed that half of my 500 gb SSD is already taken up, about ~220 gb. Yet, when I highlighted all of the folders in my C drive (including hidden folders) and checked their combined size was only ~50 gb.


After a lot of searching, I found that the "system" files are supposedly 170 GB. This is as reported in Settings -> System -> Storage -> "Show more categories" -> System & reserved. (See screenshot.) This, of course, makes no sense. Even being extremely generous, there's no reason the system files should be more than 70 GB. Note that the system files should not include any windows update stuff, any apps I've installed, or anything involving system restore, as these are all different categories.


I've noticed, when searching other threads, that there is some canned advice that people tend to give which is clearly not applicable here. So, before you type anything:

  • Do not suggest Disk Cleanup. Aside from the fact I've already done this, if you read the above it should be clear that it won't fix this problem.
  • It seems very unlikely to me that there is some file buried deep in the C drive that I have access to and can delete. If there were, it wouldn't make sense for windows to report that all of the files in my C drive are only ~50 GB. In any case, I've checked a couple such files, like Windows.edb, and they weren't large.
  • Do not suggest deleting the hibernation file. I've already done this.
  • Do not suggest checking system restore, unless there's some reason system restore might end up taking more than the percentage of disk space you can set as its maximum.

This computer is brand new -- literally got it today. There's clearly a deeper problem here than any of the typical issues listed above.


Note that third party programs like TreeSize and WinDirStat do not show any appreciable difference in the size of the files on my C drive.
