What is the blue screen I see when Windows starts up?
This is most likely DiskMagik’s Boot-time defrag defragmenting Windows boot files (e.g. pagefile, hibernation file, etc …). It is a good idea to enable this feature because it cannot be done during normal defrag while Windows is running.This can be enabled or disabled (default) by opening the program Configuration options accessible from the main Edit menu. Use the little arrows at the top right to arrow over to the Service-Defragmentation tab and here you can enable or disable the Boot-time defrag.
