If you install the google stream drive, you can run into some problem regarding drive lettes, it will shift randomly after a reboot, or it will use a drive letter you have reserved for network drive.

You can mitigate this by adding this registry key.

Save as a gdrive.reg and doubleclick. Remember to edit DefaultMountPoint, according to your likings.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Google\DriveFS]
"DefaultMountPoint"="X"
