Make Windows Picture and Fax Viewer a Media Player

Do u Know u can make your Windows Picture and Fax Viewer
(the one which is default for viewing ur pictures) for viewing movies also.
Just Play any movie with ur movie player full screen.
Take its Screen shot(Press "Print Screen SysRq" key to the right of "delete key"...
... Open Paint select, right click and paste)(save it as xyz{not recommended})
By default it will be stored in My Pictures as a black thumbnail.
Just open your video file. Go to my pictures> xyz> double click it
and ur video will get played. To view it full screen press slide show button,but pause it.
sometimes it gets played in the thumbnail view itself.
