You just brought up a Powershell prompt to navigate to the Exchange install folder, or perhaps the Exchange scripts folder.  Lets see… cd \program[tab complete].  cd Micro[tab].  “dir”  cd Exch[tab].  “dir” cd v[tab]….

And you think to yourself, “I’ll have that path memorized one of these years…”  But wait! Those smart Exchange developers knew you would probably need to go here often, so they went ahead and put those paths in the $exbin and $exscripts variables.

[PS] C:\> cd $exbin
[PS] C:\Program Files\Microsoft\Exchange Server\V14\bin>

-or-

[PS] C:\> cd $exscripts
[PS] C:\Program Files\Microsoft\Exchange Server\V14\scripts>

You’re welcome. :-)
