Normally, it will install and activate that service and its driver by default. Alternatively, you could reinstall the Reflect application completely. Even if the driver file is present, it's possible that it may have been corrupted somehow. If you're able to boot the machine at all, you can try running C:\ProgramFiles\Macrium\Reflect\MrcbtTools.exe to disable/uninstall and then reinstall the Changed Block Tracker (CBT) service. Windows will BSOD if a kernel mode (start=0x00000000) driver is called for loading but unavailable.
There were some early problems with the Reflect v7 release whereby that device class filter service got entered into the Windows registry without properly installing the required driver file, but that issue should have been resolved in the current release (version ). That's probably worth opening an actual support ticket with Macrium about, since they may want to request the minidump or even full memory dump file that BSODs leave behind to help them determine root cause.īy Arvy - 9 June 2017 9:46 - When you say that MRCBT.SYS is named as the culprit what's the exact message?
