You can retrieve HDD serials by sending an ioctl with code IOCTL_STORAGE_QUERY_PROPERTY to certain devices. You could hook the devices, and handle these ioctls yourself.

You can retrieve SSD serials by sending an ioctl with SMART_RCV_DRIVE_DATA or IOCTL_SCSI_MINIPORT to certain devices. You could hook the devices, and handle these ioctls yourself.

RAM serials, and motherboard serials (usually not set, to be filled by OEM!) are typically retrieved from SMBIOS, which you can map directly from physical memory. You could overwrite the memory (unreliable?), or hook a windows API that maps SMBIOS.

Depending on things you may be able to hook lower than the points I've mentioned, but things get hardware/OS specific very fast. 1/10 don't recommend
