Windows 10 Fantom space fully utilized
Nether Malwarebytes or chkdsk resolved the issue. It seems the problem might relate to Windows itself. When I inserted a C disk into another PC a few weeks ago, about 50GB of space disappeared, and now it’s happening again. It could be that Windows mistakenly reserves 50GB as it assumes a new Windows installation is underway, similar to how fresh Windows 10 would occupy around 50GB. I didn’t want to do anything, but the only likely fix might be reinstalling Windows.
