Specs: Windows 10
So I found windows posting a notification that my D drive is almost out of free space, I was astonished at this because I don't have a D drive on my laptop, only the root C drive, I also didn't have any external storage connected, I opened cmd as an administrator and wrote : "CHKDSK /R D:" and got this back:

The type of the file system is NTFS.

✔ Best Answer
It's likely the 500MB Win10 System Reserved Partition. Somehow it was made visible:

D drive on most manufactured systems are the factory recovery partitions and are usually hidden to the user so they are not accidentally deleted or overwritten. It is best to ignore the partition and the warning about it.

You have to be a little bit crazy to keep you from going insane.

It seems that the Windows 1803 update created this "bug", thank you all for your help.
