I have a win 7 AIO preactivated single ISO image file ( 3.71 gb ). Can i slipstream win 7 sp1 exe files with both 32 and 64 bit images into it through win toolkit ? If yes , then how ?? If no , then how to do it first into my ISO images ?? I have used win rt 7 lite , after all customization , the final image does not save successfully to my desired location at the end ..
