Rad Studio XE10 (BUG on Windows10!)

After installing your RAD Studio 10 and XE8, I noticed on Windows 10 Pro (Home) to create an image of a error, an ordinary partition (drive G) - has become a system disk! Instead 35 Gb, 448 Gb need to reserve! Probably I think that the program has a symbolic or hard links, but I could be wrong, help with this bug.
