Windows 7, 8 and 8.1 owners now have the option to update their software to Windows 10 online without installing from scratch. At the same time, it is not recommended to do a clean installation of Windows 10 due to the possible loss of the license.
Until recently, it was possible to reinstall a version of Windows from scratch, having previously saved all the necessary information on a disk or flash drive. The official version of Windows 10 does not require a clean installation and invites users to update without changing their data and removing previously installed programs through its online service.
Owners of licensed Windows 7, 8 and 8.1 should not perform a clean installation of Windows 10 due to the fact that their OS after updating may lose the activation code and become an unlicensed version. When updating the software online via the notification center on the Windows 10 taskbar, the license code is automatically changed and activation occurs.
The problem of a clean installation of the OS was also noted by the Microsoft developers themselves, who admitted that when updating their version from scratch, legal keys from previous systems would not be suitable for activating a new one. That is why it is recommended to wait for the reserved version and install Windows 10 using a free Windows app.
When faced with the problem of activating Windows 10 after updating from scratch, you need to download and install the version of the operating system yourself that was previously installed. Then activate it with your existing license key.
After the automatic online update of the reserved Windows 10, users receive a new key, which must be remembered and used in case of reinstalling the system from scratch in the future.
