We're running the latest version of Windows 10 on an ancient decade-old Toshiba Satellite laptop, favored by Paleolithic Luddites. This slow-but-steady machine has suffered zero failures, save for a hard drive which gave up the ghost three years ago. Same was replaced with a 300-Gig model, which has performed satisfactorily. We run CPUID's HWMonitor, mostly to keep an eye on internal operating temperatures, but we pay attention to space utilization on the C drive as well. We also run Windows Resource Monitor to evaluate real time RAM and CPU usage. A full complement of protection software always is activated on our Firefox 68.0.1: uBlock Origin, NoScript, Ghostery, and Privacy Possum.
My question is this: can anyone explain the following rather large differential in C-drive space utilization? Before installation of Windows v.1903, 12% of hard drive space was occupied. Afterward, 20%. Now, out of nowhere, 11%. These are nearly 30-Gigabyte swings! (No data seems to be missing and my wife doesn't surf porn sites as far as I can tell.)
I should add that I run Piriform's CCleaner and Defraggler on a weekly basis, and especially after large software downloads. Running these does not correlate with the rather large differences in hard drive space utilization, however, and I'll be durned if I can find a reasonable explanation.
Anyone have an idea?
