(#408 gman) holy crap. (Penny likes her's on a cracker) I don't feel like reading through the hundreds of posts of bs that have made their way onto this thread. so just in case no one has given The_Ghostess_Lola the simple and real answer as to why you cannot make a move called "uncastle", I will now risk repeating what has already been said.
There are 2 reasons you cannot uncastle, and one way you can when you need to.
reason 1: there is no move called uncastle. (So. It doesn't even need a name actually - just to move back.) you said it yourself it isn't a move allowed to you by the rules, but just to clear up the ambiguity about a pawn being the only piece unable to return to its original position...
Reason 2: You are not allowed to move 2 pieces in one turn. (Yes you are. You actually move (3) when promomorphing - your pawn captures a bishop, say, then you make it a queen. See ?....you moved (2) of your own pieces & (1) of your opponents !) Castling is the only exception to this, period. the rules say so. (Nope. Don't believe him everyone.) Therefore, by "uncastling" in 1 turn without another written exception you are breaking the rules. and all other pieces that are allowed to return to their original positions also have to do so through some series of legal moves.
now the good news for those times when you don't want your king in the corner anymore and/or you want your rook back to the a or h ranks. in just 2 moves you can get your pieces into a roughly "uncastled" position. (That's not good news. It's lousy news. It's too slow.)
so to recap, uncastling isn't a thing BECAUSE it isn't in the rules, (then let's not call it that. I don't really care.) and anything not in the rules is basically not allowed, (Not True. You need to familiarize yourself with the "book". Open it. Study it. Get back to us.) like say dropping in pieces that you've captured to use as your own. but you can "uncastle" if you use multiple legal moves to do it. got it? can we please lock this thread now? (At this point ?....I care not if we do.) can the hundreds of off topic or combative and non-helpful comments stop?
