Fix fltmgr.sys Blue Screen on Windows 10

Fltmgr.sys is the process code for the Filter Manager file which is responsible for making sure that all files and folders saved in the hard drive are stored at the correct position. In case this process fails, the system would cease to work, thus pushing towards a Blue Screen of Death error:

SYSTEM_SERVICE_EXCEPTION (fltmgr.sys) Blue Screen error
