After that, I noticed that the PBR Image partition took 277GB of my hard drive, then it has 80GB Free space, there's no option of shrinking the volume of it. After a year or so, I reset it again but this time using the Windows 10 reset feature.
I factory reset it twice already, the first one, using Dell Backup and Recovery, returned back to Windows 8.1 and I upgraded it again to Windows 10. 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.
