A few months after the purchase....It is still running good and I bought 5 more for my colleagues, so I bought all together 8 machines.  My of my colleagues need more memory while some need less.  So what I do is, for those who need more, I took the 4GB RAM out from their machine and put it in the machine of the colleague who needs less.  So 1 machine got 2x4G running in dual channel with identical RAM and install a new 2x8G for the original machine.  To be honest, difference for 4 to 8 is high, but little difference from 8 to 16.  So those in a tight budget can save your money._____________________This laptop is great.  For this price, there is nothing to complain.I use this for basic computer needs at home.  What I will do with is just Office, surfing, youtube, netflix.  This computer handles it really well, all very smoothly.What I like most is the screen.  It is IPS.  At this price point (310 for me), most laptops are bundled with TN display, which be honestly is a deal breaker.  The screen here is gorgeous.  I do not see much difference to my gaming laptop which cost me thrice.  Sound is good, keyboard design average.  I don't like the small num pad.  Some people complained on the backlight, but I don't need this function.  But the num lock indicator, however, is important but wasn't there.On the spec, there is just 4G of RAM.  You can, however, upgrade it easily.  There are 10 screws at of back.  Open it and you can add another slot of RAM and another HDD.  My recommendation, upgrade to 8 or 16G and add another SDD drive immediately after the setup is done as 128G storage will not be enough.  For gaming, I am yet to test it, but at 310, don't expect anything.Ar..  the Windows S issue, google Windows S Switch and you will know how to change it back to Windows 10 Home.  It is just a few clicks and a few minutes.  Everyone can do it.After all, a great computer.  My family members ordered 2 when they see mine.  Highly recommend.
