Hi and welcome to TSG.
Is this the C drive giving the notifications ? If not which is it or is there no drive letter mentioned ?
If it is C try running disk cleanup - in windows/file explorer right click the C drive > Properties > Disk cleanup button.
Run it with the default settings first then tell us how much space you have on the C drive afterwards and how large the C drive is.
