How to Reinstall System Win10 Pro

Although the Windows 10 upgrade process is going well for most Windows 7 and 8 users, it has caused problems for others. Upgrading from one version of Windows to another is rarely a good idea. Files left by the previous operating system often cause problems, and changes made to these files by other applications can also cause problems.

This is why the usual recommendation for installing a new version of Windows is to perform a "clean" installation. To reformat the hard drive before installing Windows, you only need to reinstall the application and copy the document, which will allow you to restart and run. However, there is a big problem when doing this with Windows 10. First of all, anyone upgrading from Windows 7 or 8 does not have a Windows 10 installation disc-the upgrade is done via download. Second, the Windows 10 upgrade does not provide a product key, so it cannot be activated after a clean installation. Fortunately, there are ways to solve this problem.

After a clean installation, the adapter may not work with Windows 10's own drivers.
