Sudden increase in available free space on C Drive overnight

[white oracle]

I seem to have gained upwards of 25 GB of free space on my C drive overnight. I haven't uninstalled or removed anything and from a cursory glance, all the software that I regularly use are still there.

I'm running Windows 10, the C drive is an SSD and Windows storage sense is turned off.

Is there any way to confirm if it was regular windows maintenance like cleaning old update backups or restore points? Would the event viewer or some other logfile show a record?

idk if there would be logs for that tbh, u can check out what's taking up space on ur drive with wiztree/treesize tho and see if ur missing anything
