Most likely its restore points.
But there can be other causes, just as in Vista. Hard Disk Space - Free Up and Recover

That's the normal size for a 1TB drive. What you're seeing is the difference between binary (240) and decimal counting (1012 ).
HD Manufacturers: 1000 Bits = 1 Byte and 1000 Bytes = 1MB and 1000 MB = 1GB and 1000GB = 1TB
1000 X 1000 X 1000 = 1,000,000,000,000 or 1TB
Windows: 10 24MB = 1GB
1,000,000,000,000 / 1024 / 1024 /1024 = 939.3225746154785
(I did that in my head, so it might be off in the last decimal place.) <= Big Fat Lie
The other ~.9 etc is the 100MB System Reserved space at the beginning of the drive.  Terabyte - Wikipedia, the free encyclopedia | | My System Specs | | System Manufacturer/Model Number Self

Check out this excellent tutorial from Brink: Hard Disk Space - Free Up and Recover
On today's large hard drives, shadow storage at 10-15% can easily eat up 10-15GB of a 1TB drive.
Add that to the way drive space is calculated as explained by profdlp, it's not hard to see where 46GB went "missing". | | My System Specs | | System Manufacturer/Model Number HP Pavilion Elite 495UK
