A DESCRIPTION OF THE PROBLEM :
Tilde resolves to the working dir instead of intelligently resolving to the user home dir

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
A user enters their home directory in a config file using a tilde (~).
This doesn't resolve to the user home when on Windows.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect ~ to resolve to user home on Windows.
ACTUAL -
It resolves to the working dir

REPRODUCIBILITY :
This bug can be reproduced always.
