Windows 10 Guest additions 6.0.2 scramble drive mappings into shared folders

[BBoyar]

Running Win 10 Pro (October 2018 Update, build 17763) on both host and guests, updated host from 5.2.22 to 6.0.2 with 6.0.2 guest additions. Upgrading guest VMs to 6.02 guest additions scrambled the mapped drives into shared folders. The windows drive mappings no longer corresponded to the originally assigned shared folders,. Rolling back to a previous version of the VM (which still had 5.2.22 guest additions installed restored correct behavior.

FWIW:

net use v:
vboxsrv\bbj5-c /persistent:yes net use w:
vboxsrv\data /persistent:yes net use x:
vboxsrv\bbj5-e /persistent:yes net use y:
vboxsrv\a /persistent:yes net use z:
vboxsrv\aa /persistent:yes

Reproduced this behavior on a second (and different) vin 10 pro vm: changing nothing other than upgrading guest additions from 5.2.22 to 6.0.2 corrupted the mappings into shared folders.
