If you need to reinstall, upgrade, or set up a new device with Windows 10, a clean installation is your best choice – Here’s why and how to do it.
On Windows 10, a clean installation is the best option to remove everything from the hard drive and start from scratch when your device is having performance and other issues. Using this process, you can quickly resolve startup and shut down problems as well as memory usage and apps issues. In addition, you can quickly get rid of viruses and other types of malware, fix system corruption and improve battery life.
If you’re upgrading from a previous version, a clean installation is also a good method to install the new version. Although there are several ways to upgrade, they usually don’t work correctly, and they may bring unwanted settings, files, and apps to the new installation.
It’s also a useful choice to start fresh with a copy of Windows 10 on a new hard drive that you just replaced, or to set up a new device that came pre-installed with a lot of bloatware.
In this Windows 10 guide, we’ll walk you through the steps to properly prepare and perform a clean installation, whether you’re upgrading to the latest version of Windows 10 (October 2018 Update), or you’re moving from a previous version, including from Windows 8.1 or Windows 7.
