Upgrade from Windows 8 to Windows 10

Just upgraded my Windows 8 to Windows 10 on 6th August, it's free.

From the past three days, I have been using the new Windows OS, took less than one hour to complete the upgrading, just encounter a little problem after upgrading, the display resolution is 1920X1080, however the display text is quite big, found the configuration at "Change the size of text, apps and other items:100%", from previous configuration as 150%. Problem resolved.

Overall experience is good, all the existing software installed before can be used directly in the new OS, no hassle at all.
