@epugh This is fixed and tested on Windows. Ready for review and merge. Thanks!

Can you please also cherrypick to branch_10x, and if there is an RC4, to branch_10_0 ? Thanks.

For branch_9x, I have submitted #4075 since it suffers from the opposite problem due to user-managed mode being the default there.

Will do, however I think I need @anshumg to say "yes" to branch_10_0.....
