It didn't have a pre installed Microsoft in it and the 365 one got over in less than a month .
Please do not buy this laptop so many problems in this laptop battery backup good machine very bad
If you need a compact powerful laptop this one for you with a very good build quality.And the only cons i have found that is lack of memory slot.If you need more ram you have to replace the existing one.good battery life average with moderate to heavy usage 4 hours.no heating issue.the more you use it you will feel the charm. Display is fabulous just best in this class.Its not recommended for heavy gaming due to lack of graphics card. casual gaming runs fine on it like Counter strike.Lenovo Idepapad 520S also comes with 8GB ram with a similar configuration if you have a higher budget go for that otherwise it will serve your purpose.
