The Windows installer will do the rest and will guide you through the installation process.

Run setup.exe from the USB flash drive, or from the mounted ISO, which should reside on some drive other than the system/boot device. You can reinstate these items when the install is complete. Most experts recommend that you disable or uninstall any third-party antivirus or security software (anything other than Windows Defender, in other words) and turn off Fast Boot and Secure Boot in your UEFI firmware settings (if turned on). (There’s a great TenForums tutorial on how to do this.)īefore launching into this process, make sure to log in to Windows 10 with an administrative account.

(See “ The best places to find Windows 10 ISOs ” for info on obtaining the correct Windows 10 version/build from, UUP Dump, or the Media Creation tool, and use the Windows Insider Preview Downloads page for Windows 11 builds.) I recommend building an installable and bootable USB flash drive for this purpose you may need it again sometime.

Bittedness must also be identical: 32-bit media for a 32-bit install, 64-bit media for a 64-bit install. To accomplish this, you’ll need installation media for the same edition (Home, Pro, Enterprise, or Education), language (en-US for American English, for example), and build as the currently installed edition. It means running the Windows 10 installer for the same version/build that is currently running on the machine from inside Windows 10 itself. This technique essentially involves overwriting the current OS installation with a fresh new copy while leaving your data files, settings, and preferences alone.
