It provides all required info about your pc in one place, so you can easily find what's wrong or missing with it. The interface could be better organized (it has too many tabs), but overall I like this program very much. Also there are some useful tools included in the package such as PC Health Checker and Registry Cleaner Pro which help to keep my computer healthy. If you want to check your computers hardware/software details then definitely try out Siw! It will give you everything you need to know about your current configuration of devices. You'll save time by knowing exactly how your machine works before any software installation process begins.
