Windows: stop storage service during write

Browse source 
The moment we write the block containing the partition table
Windows services will start accessing the SD card and write data
to "System volume information" folder.

If others are writing to disk concurrently this may or may not
affect our ability to eject the drive.
Stop StorSvc temporarily between us writing the partition table
(saved for last) and ejecting the SD card, just in case.

Ref #75
