What the Heck is This?

I've recently created a few restore points and tonight, for some bizarre reason, i get this error dialog notice! What does it mean? Why did this even happen? How do i correct it? Thanks you all

I've got tons of free drive space. What else could it be? thanks

Check your drive for disk space, restore points take up a lot of room.

I don't use system restore (too flaky for me) I use Macrium reflect and save image to another drive.

Flaky is correct; after restarting the PC, it fixed it back to normal.....windows 10 is spose to be the shite; it's been nothing but a headache for this user.
Thanks for being here man; you are appreciated

OK, Try running (from an administrator command prompt) sfc /scannow

and DISM /Online /Cleanup-Image /CheckHealth

and see if that picks up any system errors

Sounds like a plan; i'll get on that first thing in the morning. Thanks again!
