I must admit I never really got on with Sandboxie - so may be missing some of its benefits. With Shadow Defender in Shadow Mode for all drives/partitions is there really any benefit in running SB as well ? One of the problems when using Returnil is that other drives/partitions are still exposed but this doesn't need to be the case. The ability to exclude or commit also seems to get around the you can't save argument. So as SD doesn't slow you down but SB can is there still any reason to use SB ?
