I have a total of 994 errors in my system that needs fixing and to fix it I need to subscribe in order to avail of their programs premium offer.  I was really pissed off when I read that subscription thingy.  I tried using a different error fixing application and it stated a different number.  It showed that I have 634 errors and again it requires me to subscribe for me to be able to fix it. 

I realized that these software that clean windows registry are exaggerating the problem so that I would immediately use their product. Sometimes learning how to clean Windows registry yourself can help.  Lastly, some software is not compatible with other OS applications.  That is why for first timers it is important first to determine their compatibility or else it will cause more harm than good.
