Windows 7/8 will update to Windows 10 without reinstalling

The good news for Windows 7 and Windows 8 / 8.1 users is that they will be supported to update to Windows 10 without losing data in drive C.
Upgrading the operating system is always an exciting experience because they will be able to experience a "new breath" for their old technology equipment. However, to upgrade to the new version of Windows, users often have to reinstall, which means that it is possible to lose C drive data (the default Windows drive).
The good news for Windows 7/8 / 8.1 users is that they will be supported by an update - instead of a new one - on Windows 10, the latest operating system from Microsoft office 2010 product key. This means that users of Windows 7 and Windows 8.1 product key will not need to back up their data in C drive and can perform the upgrade process normally without losing data or wear. Although many people still encourage you to back up data to prevent the bad situation. This process is almost like receiving an OTA update on your phone.

For users of Windows XP, Windows Vista or earlier versions of Windows, you will lose data on drive C if you perform a new update or installation (the method of coping with this is copy the important data to another drive).
A few months ago, Microsoft tested the distribution of Windows Technical Preview via Windows Updates, and if that process goes well - you might get a complete Windows 10 pro product key update through this and probably will. Upgrade is free. This is a nice thing for those unfamiliar with installing Windows through the ISO file. Microsoft has also released Windows 8.1 updates for Windows 8 users through the Windows Store and the release process is very good.
Windows 10 will be ready for release in the second half of this year, but in the meantime, we will receive the January Technical Preview and Microsoft Windows event in the second half of this month.
