Thank you very much windows10
The win 7 to win 10 upgrade system can be obtained for free, the tutorial can be found on the internet.
Since using Windows 10 finally I can have email from Outlook which can be separated from the browser to the mail section.
Many more free software from the Windows Store that can be downloaded.
Surfing the web feels more efficient, in contrast to Windows 7, we have to add an anti-virus program first. In Windows 10 with the defender it is quite helpful.
Recommended apps from the windows store that are free to use:
2. PhotoScape X
4. Autodesk Scketchbook
And there are many others.
