D: Drive became Inaccessible

Recently i installed oracle 12c on windows 7 . As a security measure Installation of oracle 12c on windows requires non-administrative user .

At the time of installation i created user db1 for same . I already had user which was one less than administrator privilege and equivalent to administrator user privilege and not equal .

This step resuled in one error

D:/ drive became in accessible to all non-administrative user

Resolution

I had to login as administrator and re-create the permission for all the users whose access got revoked
