It is a very good idea to document those keys. Here is a preliminary 
list for w32:

** Most important:
  - Alt-Tab, Alt-Shift-Tab
  - Ctrl-Esc, Ctrl-Shift-Esc
  - Ctrl-Alt-Delete
  - Ctrl-Tab, Ctrl-Shift-Tab
  - Ctrl-C, Ctrl-X, Ctrl-V, Ctrl-Z
  - Ctrl-A
  - Alt-Space
  - Esc
  - Tab, Shift-Tab

** Also very important:
  - Ctrl-<arrow key>
  - Alt-<any letter>
  - Alt-Print

** More clashes:
  - Alt-F4
  - Well, actually Alt+<any key> is reserved if I remember correctly.
    MS Terminal Server, for example, uses some more.
  - LWindow, RWindow


Footnote: Because of those clashes (escpecially with Alt) I have argued 
several times to include code to allow the use of LWindow and RWindow as 
Meta in Emacs on w32 instead of Alt. (This is the low level keyboard I 
use to mention.) The normal w32 uses of LWindow and RWindow are IMHO by 
no means as important to an Emacs w32 user as the normal w32 use of Alt.
