After today's upgrade of my PC from Windows 7 Ultimate to Windows 10 I think that I was right doing this:
1. My system C: drive free space increased by 85Gb. 4-years' garbage of Windows updates was deleted, at last!
2. As a software developer I checked how Android Studio works and was pleased to see that Android 5.1. emulator with 1.5Gb of RAM started to work! So at last I can test applications on latest Android OSes using my PC. In about a year in Windows 7 I had to recheck everything on hardware devices because emulator on PC constantly crashed... (it is widely known that under Windows emulator having more than 760 Mb of RAM may crash)
3. No other changes, which would brake my usual habits. All my apps migrated, even fingerprint logon still works without any changes. I still can have Google Chrome as a default browser. Start menu has all I need and didn't change (for me) that much from Windows 7...
