The servicing stack in Windows 8.1, Windows RT 8.1, and Windows Server 2012 R2 may enable NTFS compression on some device drivers and other system files in order to save disk space. For example, this may occur after you install a Windows Update.
Because of a problem in the Ntfs.sys file, when the compressed files are loaded from a 4K sector disk, various drivers may encounter failures because of random access memory (RAM) that is expected to be initialized to zero contains random data instead.
