The most beneficial thing i like about sandbox is it's ability of making more secure my windows computer by keeping all malicious software out off them so they can't do any harm or infecting others with malware etc.. It has some limitations but nothing too bad as well if you use in conjunction its great for sure! Nothing really anything dislike abt this program just because there are no other alternatives yet which works exactly same way only better than SANDBOXIE! If u have Windows XP then go ahead give U try first before buying else wait till someone makes an alternative one otherwise dont waste ur money cause once again Microsoft will remove their support soon enough so get ready for another painfull experience :) I am using sandoxbieditor version 4.5 (build 6) running under WinXP SP3.
