Answer 1

Almost 60% of the commands I use everyday..

dv /i /t
?? this
kM (kinda undocumented) generates links to frames
.frame x
!analyze -v
!lmi
~

Explanation

1. dv /i /t [doc]
   1. dv - display names and values of local variables in the current scope
   2. /i - specify the kind of variable: local, global, parameter, function, or unknown
   3. /t - display data type of variables
2. ?? this [doc]
   1. ?? - evaluate C++ expression
   2. this - C++ this pointer
3. kM [doc]
   1. k - display stack back trace
   2. M - DML mode. Frame numbers are hyperlinks to the particular frame. For more info about kM refer to http://windbg.info/doc/1-common-cmds.html
4. .frame x [doc]
   1. Switch to frame number x. 0 being the frame at top of stack, 1 being frame 1 below the 0th frame, and so on.
   2. To display local variables from another frame on the stack, first switch to that frame - .frame x, then use dv /i /t. By default d will show info from top frame.
5. !analyze -v [doc1] [doc2 - Using the !analyze Extension]
   1. !analyze - analyze extension. Display information about the current exception or bug check. Note that to run an extension we prefix !.
   2. -v - verbose output
