As far as I know, The fastboot.sys driver preloads files that Windows is known to need on startup. It only uses memory that would otherwise be unused and the driver releases the memory as soon as either they are no longer helpful or the system is under memory pressure. To remove fastboot.sys, we can go to C: windows>system32>drivers to find fastboot.sys and then delete it. If you can’t delete it, you can rename its suffix, .sys to .txt. The memory will be made available for other uses as soon as it is needed for another use. There is no problem to solve. For the unknown driver that consumes your memory, you can use a tool called Poolmon when you feel the driver is using your memory to detect it. How to use poolmon, please see:

Fastboot.sys (FBr0) and an unknown driver consumes approximately 7 GB. How can i remove Fastboot.sys and how can i find unknown driver's name? In settings, I disabled Fast Boot but i can't find anything like Fast Run or Fast Boot in BIOS. I have used sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth commands but nothing changed. In total i have 16 GB memory (8x2). Thanks in advance. I have asked in Microsoft Community but they suggested that i should ask in here.
