It was originally Windows 8.1 Single Language and downloaded the free upgrade to Windows 10 of Microsoft. I have a 2014 Dell Inspiron 3442 with 1TB hard drive.
Here is a true example from the Dell community. Some users reported that the PBR image drive can consume hard drive space up to 278GB. After analyzing extensive user reports on the Dell communities and forums, we find that the PBR image full issue often occurs after upgrading from Windows 8 to Windows 10 or resetting Windows 10.
