Does anything appear to be missing?

It was most likely deleted shadow copies of existing restore points. these are images of the disk taken and stored incase you need to revert to a previous date. These can be deleted by doing advanced system clean up and removing system files will delete all the old shadow copies. These can easily take up to 150G + of storage if you have a lot.

No anything is missing, everything are fine just realized this free space,my paging file is off, shadow image this is restore file?but my system protection is off on local disk c

if you are worried about it, go back to one of your previous restores that is if you still have them. C may have the pagefile off, but that at most will take 1-30g of space, the only thing possible to take that much space and disappear without you even realizing it would be your shadow restores, which is your previous versions.

you can check this by right clicking, properties on C, now go to previous versions tab. If there are not any then you know where a majority of it has gone, its been deleted. if there are you can restore to a point just a few days ago and look on C with a disk analyzer and see whats taking so much space. Then you can choose to remove it or leave it.

If c is your desktop aswell you may have had an extremely full recycle bin. Its never fully emtied until you empty it. Im not sure of the storage capacity of one but i would guess its quite large.

If anything your computer still works like normal, and now you have plenty of free space.
