umm, not quite. That will only do it for remote drives. See my first post in this thread.
I'm not sure what you mean by "remote" drives, but it does the same thing in "My Computer" that PhilB66 shows in Tweak UI, earlier in the thread. I have been using it with success for several years now where I work.
This will *not* affect how drive letters appear in the Windows Explorer *application*, if that is what you were looking for.
Note also that the MS article you point to, earlier in the thread, points to 2 reg keys (policies) different than the one which I suggest, so perhaps they both work.
