After windows 7, windows 8 came with lots of new features as its biggest popular feature was touch system. people were attracting too towards the new touch system of windows 8. I was also a victim of it. I also started using windows 8 in my lenovo all in one pc which was touch supported skin. I found a lots of issue in it. I don’t support all applications. At the time of running any external application as game stops there for a while. windows 8 was unable to provide its software security updates. overall all its worst to use. If any had buy windows 8 cd spending the cost he or she wil have in a great loss. after this windows 8.1 came which was good but not even so successful was as windows 7. but now you get windows 10 with a lots of amazing features.
