Got this as a replacement for my very old dying Dell with Windows 8. I really like the computer it's light, it's fast and it was a great price!  Figured I'd get used to Microsoft and Windows 10 preferred search engine, email and all their other preferred programming.  Discovered that every one of their game apps, I searched for Scorpion/Sudoku/others and all had one star reviews, not to mention a very small selection!  So I started to download all of my other favorites such as Gmail, Chrome and most importantly KINDLE FOR PC.... Every single one stalled and said I had to remove S MODE from the computer. So, being a "older person" I looked it up on YouTube... and found that it is a Microsoft safety feature, and once you turn it off you cannot turn it back on. I have been assured by several younger family members that is no big deal to take it off, if I have good virus protection. BUT it is still greatly frustrating to purchase something brand new and then I have to remove a program that blocks some of your favorites. PS... It allowed me to download Amazon Music...but not Kindle... ridiculous!!!
