The Windows 7 version of Minesweeper introduced a feature that allows you to save games to its own format. It ends with .MineSweeperSave-ms.
Possibly it's the same thing for Vista.
[edit] Identification
There are a few parts here.
The first part (the header), begins with signature RGMH, and then contains some binary data.
After that, it contains the UTF-16 encoded string 4D 00 69 00 6E 00 65 00 73 00 77 00 65 00 65 00 70 00 65 00 72 (Minesweeper) and a lot of NULs.
Then, the next string appears: 4D 00 69 00 6E 00 65 00 73 00 77 00 65 00 65 00 70 00 65 00 72 00 2E 00 4D 00 69 00 6E 00 65 00 53 00 77 00 65 00 65 00 70 00 65 00 72 00 53 00 61 00 76 00 65 00 2D 00 6D 00 73 (Minesweeper.MineSweeperSave-ms) which is the filename always uses, and lots of NULs.
The second part is a PNG image, which is the thumbnail image (basically a small visual snapshot) and some binary bytes.
The third part is a XML file for the game's board.
The header for the game's board XML is <Board>, then <SaveVersion>3</SaveVersion> defines the version of the save file (for Windows 7, it's always 3), then the number of mines, width, height, difficulty, etc...
