Windows 10: System files taking up 150 gigs of space, need help

Surely this cant be right? I have run WinDirStat and there is 150 gigs of space just missing, any clue how to clear that up?

:)

 

Should my system files really take up 300 gigs worth of space?

Hi, it's my first post and all so I'm just going to make this short. Should my system files really take up 300 gigs worth of space? I downloaded windows 10 through bootcamp on my mac through USB. I dedicated about half of my computer hard drive space to Windows (about 450ish gigs). But in actuality, I only have about 150 gigs because my system files take up a majority of the storage. I'm assuming that this isn't supposed to happen (but it would really suck if it did)

All help is appreciated!

 

System and Reserve taking about 150 GB of Space

I just uninstalled and reinstalled Windows 10 on a new SurfacePro. There's only two applications reinstalled and 0 files. The System and Reserve are taking about 150 GB of space. Something seems wrong.

Normally, I'm an Apple user. But I need this device to work with Zoom for my classes.

 

System Taking Like All of my space ._.

Windows File Explorer is not great at finding out where your hard drive space is being used . . .

• Click HERE to download a small free utility Called TreeSize.
  
• Run that utility as Administrator
• Point it to your C Drive
• Let the list of files/folders build
• Expand out the folder(s) that are taking all your hard drive space
• Please provide a screenshot of the resulting window in order for us to make a better analysis of what is happening with your system and suggest a remedy
